    Postfix problem


    Hello,


    I am writing you concerning the following issue with "postfix",
    any e-mail message over 3 MB doesn't go through and I receive the here below message:

    "An error occurred while sending mail. The mail server responded: 5.7.1 Your email is rejected - probably spam!. Please check the message and try again"


    Everything goes well with messages under 3 MB.

    Please advice on what settings should I change in order to allow traffic over 3 MB - to increase this limit up to another level.



    Thank you in advance,
    stefan

    Hi,

    You can see what setting your postfix install is currently using by issuing the following command:
    Code:
    postconf | grep message_size_limit
    To change the setting to some other value, open the main.cf file in your favourite text editor (it's often at a location like /etc/postfix/main.cf) and either edit or add size as you want.

    Code:
    message_size_limit = 10240000
    and Then reload postfix.

    Thanks

    Three notes:
    - The server says: "rejected - probably spam", not "rejected - too big"
    So while the size *may* lead to this message, there could be other/more reasons.
    - Modifying the message_size_limit on your own server might not be enough. Whether you can send/receive big mails also depends on the remote mailserver.
    - If you want to allow such big mails, be aware that they need more time to process and more storage space.

    Hi,

    thank you, but why "rejected - probably spam", and how to solve this problem?
    I made a lot of changes, but

    "size_limit" is ok, but I want to send/receive mail with more than 3 MB size attach.

    Log server mail:
    "proto=ESMTP helo=<server.exemple.com>: 5.7.1 Your email is rejected - probably spam!"


    thank you very much,
    stefan

    It seems its not email size issue, might be your mails are rejecting due to your email contents. You should check it by sending any test mail > 3

    Also check you spam filter configuration and log.
    How to do that depends on the components used.

    Hi,

    I received this message: "reject: body 6Jpjs3lAKcfYY2qVZlmBk/yuNj4msocQr5L74fvLQgLeB+QAa8WcA0TzFmhjo5UrgiZDmEJO bk6j from unknown[MY IP];"

    When I tried to send the files - maybe there was a certain word considered spam.

    Next I sent different files of bigger size and it went well

    Yes, that was.

    thank you very much for all
    stefan
