Configure mail server

Requirements

  • Mail transfer agent (MTA): See also "Requirements".

  • A mail domain name for the mailing list service. See also "Requirements".

    Through the instructions in this chapter, mail.example.org will be used for example.

Instruction by MTAs

Tests

  1. Start mail user agent (MUA) on your PC or PDA.

    Note

    • If you are not allowed to use MUA, you may use telnet client instead: See also "Telnet example" below.

  2. Send any message to [email protected]. And confirm that your message will be delivered to postmaster.

  3. Send a message with a subject "help" to [email protected]. And confirm that the message will be stored into incoming spool directory (by default it is msg subdirectory in $SPOOLDIR directory).

    Note

    • If the services have already started (or once they start), this message will be removed immediately, and a help messsage will be sent back to you.

  4. Send any message to [email protected]. And confirm that the message will be stored into bounce spool directory (by default it is bounce subdirectory in $SPOOLDIR directory).

    Note

    • If the services have already started (or once they start), this message will be immediately moved into bad subdirectory of the spool.

If something went unexpected, check mail system log and configuration of MTA.

Telnet Example

  1. Open your favorite telnet tools (telnet or putty for example).

  2. Open a session to your postfix server and use this command (replace example by your addresses).

    HELO example.fr
250 yourserver
MAIL FROM:<[email protected]>
250 2.1.0 Ok
RCPT TO:<[email protected]>
250 2.1.5 Ok
RCPT TO:<[email protected]>
250 2.1.5 Ok
RCPT TO:<[email protected]>
250 2.1.5 Ok
DATA

Message-ID: <Something>
From: <[email protected]>
Subject: Hello

Hello World
.
250 2.0.0 Ok: queued as XXXXXXXXXXXXXX
QUIT
221 2.0.0 Bye

This should be enough to see if everything is ok on the MTA side.
