10) Axigen

Axigen Mail Server is a large class communication server that integrates SMTP, POP3, IMAP and WebMail services. Having very good configuration and security, it gives administrators excellent control over mail server traffic.

Many sysadmins have difficulty working with e-mail systems. Not surprisingly, a mail server is much more complex than a file server, router, or terminal server. In this article, we will look at the structure and principle of operation of mail servers, without understanding which setting up an e-mail system is quite capable of turning into shamanic dances with a tambourine.

This material contains quite a lot of simplifications and generalizations in order to give system administrators the necessary minimum of knowledge. In our opinion, it is not necessary to become an e-mail specialist to administer one or two entry-level mail servers.

For most users and novice administrators, the mail server is a kind of "black box" that, having received a letter by "unknown" ways, delivers it to the addressee and vice versa. All interaction with such a server consists in addressing the mail client to certain ports, or even through the web interface in general. However, there is a whole mechanism hidden inside, understanding the operation of which is key to successfully configuring and maintaining an email system. This is especially important for Linux server administration. Unlike Windows, where the mail server is a complete software solution and the developers have already taken care of the internal interaction, in Linux the mail server components are separate programs and you need to configure their interaction yourself.

Let's take a look at the structure of the mail server and what happens when a user tries to send mail.

The most important part of the mail server is MTA (Mail Transfer Agent - mail forwarding agent) whose tasks include receiving and transmitting mail. Very often (in Linux / UNIX) MTA is also called a mail server. MTA works on the SMTP protocol, and it alone, in principle, is already enough to create an e-mail system. Once upon a time, this was exactly the case, and to access your mailbox, you needed to have certain technical knowledge.

However, progress does not stand still, MTA, receiving a letter, puts it in the user's mailbox on the server, which the latter must access, preferably in the simplest and most understandable way. Here comes the stage MDA (Mail Delivery Agent - mail delivery agent), his task at the request of the mail client to transfer mail from the mailbox on the server. MDA can work over POP3 or IMAP, in some cases, for "communication" between the mail client and the delivery agent, proprietary protocols can be used that have advanced functionality, such as MAPI (Exchange Server).

Contrary to popular belief, MDA has nothing to do with the mail transfer process. This is the prerogative of the MTA. To make an analogy, the MTA can be thought of as the post office, which handles receiving and sending mail, and the MDA is the postman who brings the incoming mail to your home. If the postman is sick, then this will not affect the work of the mail in any way, you just will not receive a letter at home. Also MDA, its failure does not lead to the inoperability of the mail server, only receiving mail by the mail client becomes inaccessible, at the same time, it can be easily accessed in other ways, for example, through the web interface.

Let's see what happens when sending mail. In our example, the user Ivanov, located in the example.org domain ( [email protected]), writes a letter to Kozlov in the example.com domain ( [email protected]). For Ivanov, the process of sending mail consists of creating a message and pressing the "Send" button in the mail client. The mail client connects to the MTA using the SMTP protocol and first of all provides its credentials. After authorizing the user, the MTA accepts the message and tries to deliver it further.

Actually, authorization is not a mandatory procedure for the MTA, but without authorization, we will get an open relay, i.e. anyone can use our server to forward mail, and spammers will be delighted! Currently, open relays are caused mainly by server configuration errors. However, it is quite possible that the MTA accepts mail from trusted users without authorization, for example, from the local network of an enterprise.

The MTA can use its own user list, system list, LDAP or AD user lists for authorization. There is also a way: POP before SMTP authorization, where the user logs into the MDA before sending mail, which in turn confirms the user's authentication to the MTA.

The next step is the MTA analyzes the service information of the letter, determining the recipient's domain, if it belongs to the domains served by the MTA data, the recipient is searched for and the letter is placed in his mailbox. This would have happened if Ivanov had written a letter to Petrov or Sidorov.

If the recipient's domain is not served by the MTA, a DNS query is generated asking for MX records for that domain. An MX record is a special kind of DNS record that contains the names of mail servers that process incoming mail for a given domain. There can be several MX records, in which case the MTA tries to establish a connection sequentially, starting with the server with the highest priority. If there is no MX record, an A record is requested (an address record that maps a domain name to an IP address) and an attempt is made to deliver mail to the host specified there. If it is impossible to send a message, it is returned to the sender (placed in the user's mailbox) with an error message.

We will not consider the work of the receiving server, we will assume that everything went well, Kozlov received a letter from Ivanov and wrote him a reply. The server serving the example.com domain does exactly the same thing and tries to send mail to our server. Having received an incoming message, the MTA, as in the case of the local sender, checks the recipient's domain, if it is one of those served by the MTA, message processing continues, otherwise the server refuses to accept mail. After checking the domain, the recipient is checked, if he is present in the list of users, the message is delivered to his mailbox, otherwise there are two options: refusing to receive a message or receiving a message in the general mailbox (administrator's mailbox). On the one hand, this setting increases the number of received spam, on the other hand, it allows you not to lose letters with errors in the spelling of the address.

Another anti-spam measure is to request a PTR record. The PTR (Pointer) record associates an IP address with a domain name. By requesting PTR, the MTA accepts mail only if the sender's domain matches the domain of the sending server.

Let's consider an example in more detail. A certain spam server spam.com is trying to send letters with a fake sender, allegedly from the example.com server we know. In the case of filtering by white / black lists, such a letter will be delivered, since the sender is a user from a trusted domain (which is what the spammers expected). In order to combat spam, the MTA generates a PTR record request for the IP address of the sending server, which it reports during the SMTP session. For y.y.y.y, the PTR request will return the spam.com domain name, which does not match the sender's domain, which will cause the message to be denied. At the same time, messages from the server x.x.x.x will be received, since the domain from the PTR record for x.x.x.x (example.com) matches the sender's domain.

So, the message is received and is in the user's mailbox. How do I read it? Mail storage, where user boxes are located, can be organized in a variety of ways: from commonplace folders and files to a database. Without technical knowledge, you will hardly be able to read your own mail. But does this have to worry the user Ivanov? For him, the process of receiving mail is reduced to pressing the "Receive" button in the mail client.

To receive mail, the client establishes a connection with MDA using the POP3 or IMAP protocol, making sure to send data for authorization. MDA checks the user's presence in the lists and, if successful, sends to the client all new messages in his mailbox. User Ivanov receives his correspondence and can work with it in a convenient way.

This concludes our article, we strongly recommend a thoughtful reading and assimilation of the material presented in it. Subsequently, when considering the practical implementations of mail servers, we will submit material on the basis that the reader has knowledge of at least this article.

Anyone who works as a system administrator in a small organization knows that everyone needs emails to work, even if your company has only one mailing address to which mail comes. But how to make the letters read by everyone, even those users who do not have access to the Internet, we will consider this problem here with you.

First, we need some kind of mail server. I think it makes no sense to buy cool mail servers in a small organization, and, of course, no one will give you money for this. But a small program comes to our rescue, which is a mail server, but at the same time it is free and easy to configure. This is Office Mail Server ( You can easily download it on the Internet.).

Office Mail Server (OMS) - free mail server for Windows platform, supports POP3 and SMTP mail protocols. The meaning of the program is simple, the computer on which this program is installed connects to the server, be it a regular Yandex, Mail or a mail server of your company's head office ( if your organization is a branch) from which you want to pick up letters. After receiving letters, the Office mail Server scatters them among users, who will later receive letters via the local network using a regular mail client, for example The Bat or Mozilla Thunderbird. All this gives us the fact that only one computer with Internet access is enough in the local network, and everyone can receive letters.

Installing Office Mail Server

Installation of the program is simple, just install the program by running the exe file and you can start it right away, after starting the program the following window should appear ( if the program was installed correctly).

Description of Office Mail Server settings

Now let's look at the description of the program settings from the author of the program himself:

Mailbox folder - the folder where the mailbox files of users will be stored. If you wish, you can enter a different path to these files, but the folder you specified must already exist.

Outbox queue folder - the folder where the files of messages prepared for sending to an external SMTP server will be stored. If you wish, you can enter a different path to these files, but the folder you specified must already exist.

Local domain - used only for internal bogus email addresses - for example, if you leave the default ("mydomain"), all local users will have email addresses in the form " [email protected]", Where user is the username.

Log file size, KiB - here you can set the maximum size of the log file (ofmsrv.log) in the range of 0… 999 kibyb. If the value is set to 0, then no logging is performed. Otherwise, the file is limited to the specified size. I highly do not recommend setting the size above 100 KiB - this can lead to a noticeable decrease in program performance.

POP3 server port number - the generally accepted port number for a POP3 server is 110. However, if this port is already occupied on your computer by another program, enter your value. You must restart the program for this parameter to change.

SMTP server port number - the generally accepted port number for the SMTP server is 25. However, if this port is already occupied by another program on your computer, enter your value. You must restart the program for this parameter to change.

POP3 and SMTP servers timeout (sec) - time interval in seconds after which the server considers the connection to the mail client to be broken if no commands are received from the mail client. For mail servers on the Internet, this parameter is set for 10 minutes (!) - taking into account that the connection may be slow. However, in a local network such a long blocking is absolutely useless, a few tens of seconds is quite enough. You must restart the program for this parameter to change.

Maximum sent message size, KiB - allows you to set a limit on the size of messages sent through the program's SMTP server. This parameter affects only messages that go "outside", but the restriction does not apply to local messages. The size is given in kibibytes. If size limitation is not required, enter "0".

Use IP filter to restrict access to servers - by checking this box, you will restrict the ability to connect to servers from the Internet in order to use the SMTP server of the program to send SPAM. SMTP and POP3 servers will only be accessible from IP addresses that have successfully passed the filtering algorithm:

1. If there is no entry allowing access, access is denied (Exit).
2. If there is an entry denying access, access is denied (Exit).
3. Allow access.

IP filter - this button calls a dialog box in which you can configure the ranges of IP addresses from which it is possible to access the SMTP and POP3 servers of the program. By default, OMS creates a filter configured to allow access only from IP addresses allocated to local networks :

• 127.X.X.X mask 255.0.0.0 - localhost
• 10.X.X.X mask 255.0.0.0 - class A local network
• 169.254.X.X mask 255.255.0.0 - class B local network
• 192.168.X.X mask 255.255.0.0 - class B local network
• 172.16.X.X mask 255.240.0.0 - 16 class B local area networks

WAN routers block all packets from / to such addresses, so your servers will be effectively protected from intrusion.

If the words "IP address" and "Subnet mask" scare you - it is better not to touch the IP filter settings First read the literature on setting up TCP / IP networks.

Local users - a list of registered local users who are able to connect to OFMSRV. Each user has a unique username, an optional password to connect to the POP3 server, and an optional external alias ( which will replace the dummy internal email address when sending a message to the Internet, which will allow the addressee to correctly use the message reply function).

There are two special users - one of them is POSTMASTER. This is the user responsible for the operation and maintenance of OFMSRV. He receives special messages generated by the system in case of an error, as well as all incoming messages, the addressees of which the sorter could not determine ( unless the sorter is explicitly told which local users to send such messages).

Another special user is DEMON. This is not a real user, but a strange creature that lives in OFMSRV. The daemon cannot receive messages from the Internet, no one can connect to the POP3 server under his name and read his mailbox. But each local user can send any message to the daemon, and when the daemon eats it, it will start a communication session with an external SMTP / POP3 server to send the accumulated outgoing mail and read the incoming one. This is done to enable remote start of a communication session, but it can be done manually from the OFMSRV menu without waking up the daemon.

Postmaster and daemon cannot be deleted.

In addition, there is a user "Boss". It receives copies of all messages sent through the program's SMTP server, which allows it to control and archive outgoing mail of all local users. Any user other than DEMON can be assigned as the "boss", but it is better to assign a special name. Do not forget to periodically clear the "boss" mailbox - otherwise, over time, the performance of the program may noticeably decrease. Also, do not forget that such interception of mail violates human rights, but in some organizations it is simply necessary.

Adding new users and changing their data is done by the corresponding buttons of the dialog box.

To configure communication with an external mail server, use the menu item " Settings-\u003e Communication» ( you will see the following window).

• SMTP server - ip address of your computer on which this program is installed;
• SMTP port - port of the mail server;
• LAN connection - check this box if you are constantly connected to the Internet ( via local network), or through the Winsock Proxy client. When this check box is cleared, the Use this connection ( only if "Remote Access" network accounts are registered on the computer);
• POP3 accounts - here the remote mail server is just configured ( can configure up to 100 accounts).

To sort letters between users, you need to use the following menu item " Setting-\u003e Sorter". The idea behind the sorter is to sort the letters that OMS receives by the users who should receive these letters.

Then you press the add button and put “to” in the “if the header field” field, and in the “contains text” field, write the address from whom you received the letters and finally add users who need to deliver these letters ( you can see more detailed setup instructions in the folder with the program after its installation).

Now you just need to configure the mail clients of users who want to receive letters. This is done very simply, where you specified the transport settings ( SMTP and POP3 servers), You already write your server address, for example, the local ip address of the computer on which OMS is installed, and specify the user and password ( exactly the ones that you started in the OMS program).

That's basically all, thanks to this program you can easily reduce the Internet traffic in your organization, and in general you simply do not need to configure the Internet on user computers.

For those who want to try their hand at self-installing and configuring a mail server, we will consider the process of a step-by-step installation of a mail server based on a Windows Server 2003/2008 / server and hMailServer software; Let's go through the stages of organizing and configuring the DNS service within the same server, and adding our mail domain to the server.

The material uses hMailServer software version 5.0-B305.

Installing and configuring a mail server

Configuring email clients to work with email

E-mail is a service that allows you to exchange electronic messages through a computer network.

You can work with e-mail using mail program (mail client) installed on the user's computer or using a browser using the web interface.

Mail program (e-mail client, mail client) - software installed on the user's computer designed to receive, write, send, store and process the user's e-mail messages. Mail programs usually provide the user with numerous additional functions for working with mail (selection of addresses from the address book, automatic distribution of messages to specified addresses, etc.).

The simplest email client is Microsoft Outlook Express.

It is included in the standard Windows package (starting with Windows 98) and therefore is available on every computer running this operating system. In Windows Vista, it was replaced by the Windows Mail client. The Bat! Is also very popular among users. and the free Mozilla Thunderbird email client.

In the last article, we looked at how to configure and run a mail server in its class. Now let's start configuring email clients and testing the work of our local mail.

In order for the mail client to be able to send and receive mail, in its settings you need to specify the addresses of the servers of incoming and outgoing mail, as well as the account parameters for connecting to the mailbox (name and password).

Configuring mail clients must be done on all computers of users who need access to e-mail through the mail server.
