    Защищаемся от почтового спама!


    Защита от почтового спама!
    Для этого нам понадобиться добавить некоторые строки на main.cf  и создать пару файлов!
    Для этого откроем файл для добавления /etc/postfix/main.cf:

    # H/B Checks
    header_checks = regexp:/etc/postfix/maps/header_checks
    mime_header_checks = regexp:/etc/postfix/maps/mime_header_checks
    body_checks = regexp:/etc/postfix/maps/body_checks

    Итак создаем директорию maps и файлик под названием body_checks

    # mkdir /etc/postfix/maps
    # touch /etc/postfix/maps/body_checks


    После чего вносим записи в файл:

    # This will reject emails where any line contains eight or more script/comment tags.
    #/(]*>).*){8}/ REJECT Your email contained a lot of script tags. Please
    # correct this (try setting your mail program to use plain text) and resend your message.
    # This will reject emails with script/comment tags that are in the middle of a word.
    #/^.*[a-z][a-z]/ REJECT Your email contained wrongly placed script tags.
    # Please correct this (try setting your mail program to use plain text) and resend your message.
    # This will reject some variants of Sobig viruses
    /^RSLxwtYBDB6FCv8ybBcS0zp9VU5of3K4BXuwyehTM0RI9IrSjVuwP94xfn0wgOjouKWzGXHVk3qg$/ REJECT Your email looked like it \
    contained a virus. Please run a virus scanner on your computer and try again.
    /^TVqQAAMAAAAEAAAA\/\/8AALgAAAAAAAAAQAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA$/ REJECT Your email looked like \
    it contained a virus. Please run a virus scanner on your computer and try again.

    ## Bad worlds

    /viagra/ REJECT Body Spam Rule 2

    /V~I~A~G~R~A/ REJECT Body Spam Rule 6
    /p"enis/ REJECT Body Spam Rule 7
    /e"nlarde/ REJECT Body Spam Rule 8

    Далее создаем файл по названием header_checks и вносим записи:

    /^Subject .*Free Money/ REJECT Spam Header Rule #1

    Далее нам осталось создать файл mime_header_checks

    # This entry will reject messages with attachments that could be dangerous, and will inform the sender of what type of attachemnt was rejected.
    /^\s*Content-

    REJECT Files attached to emails that contain or end in "$3" are prohibited on this server as they may contain

    При необходимости вы можите сами добавлять правила...
    Перезапускаем postfix и будет Вам счастье!
