1 You can do several tests of messages entering the qmail system:

     2 

     3 1. SMTP server test: Forge some mail locally via SMTP. Replace ``me''

     4    with your username and ``domain'' with your host's name.

     5        % telnet 127.0.0.1 25

     6        Trying 127.0.0.1...

     7        Connected to 127.0.0.1.

     8        Escape character is '^]'.

     9        220 domain ESMTP

    10        helo dude

    11        250 domain

    12        mail <me@domain>

    13        250 ok

    14        rcpt <me@domain>

    15        250 ok

    26        %

    27    Look for the message in your mailbox. (Note for programmers: Most

    28    SMTP servers need more text after MAIL and RCPT. See RFC 821.)

    30 2. Remote-local test: Send yourself some mail from another machine.

    31    Look for the message in your mailbox.

    32 

    33 3. Remote-error test: Send some mail from another machine to

    34    nonexistent@domain. Look for a bounce message in the remote mailbox.

    35 

    36 4. UA test: Try sending mail, first to a local account, then to a

    37    remote account, with your normal user agent.

    38 

    39 5. Remote-postmaster test: Send mail from another machine to

    40    PoStMaStEr@domain. Look for the message in the alias mailbox,

    41    normally ~alias/Mailbox.
