    mail log is like ;

    I don't see any errors in your mail log.
    What's in /etc/postfix/transport? Did you run
    Code:
    postmap /etc/postfix/transport
    /etc/init.d/postfix restart
    after modifying that file?

    yes I run it everytime I modify the transport, relay_recipients, and relay_domains...

    in transport file;

    # TRANSPORT(5)
    abathroomguide.com smtp:[lancelot.warmlyyours.com]
    warmlyyours.com smtp:[lancelot.warmlyyours.com]

    #
    # NAME
    # transport - Postfix transport table format
    #
    .
    .
    .


    only thing I changed is ..in /etc/MailScanner/mailscanner-mrtg.conf, it didnt accept "MailScanner Work Directory = /var/spool/MailScanner/incoming" ( it says Unable to find a mountpoint for /var/spool/MailScanner/incoming. Please set MailScanner Work Directory in mailscanner-mrtg.conf to a valid mountpoint. You can see a list of mointpoints on your system by using the df command
    ) so I chanced as a "MailScanner Work Directory = / "


    also I dont use snmp because it was optional..

    in the firewall do I need to make any more configuration other than opening smtp port?

    Also in /opt/MailScanner/etc/MailScanner.conf;

    Incoming Queue Dir = /var/spool/postfix/hold
    Incoming Work Dir = /var/spool/MailScanner/incoming



    but in /etc/MailScanner/mailscanner-mrtg.conf;

    Incoming Queue Dir = /var/spool/postfix/hold/
    MailScanner Work Directory = /

    should I make work directories the same in both configuration???




    thx in advance..

    hey Falko,

    actually I found the reason why it doesnt relay the emails..


    from vi /etc/postfix/header_checks
    I removed /^Received:/ HOLD

    it relays now but this time I think it is not gonna scan it because it first hold it..scan..then sent it..

    do you think my sender restrictions rules still apply?

    Well, I have the same problem (ubuntu 6.06 installation with postfix & mailscanner).
    MailScanner runs and in /var/log/mail.info I have the same output (every 4-5 seconds same things) and NO mail delivered.

    All my emails are still in /var/spool/postfix/hold .
    As soon I stop header_checks (either removed HOLD from header_checks either comment it out in main.cf ) all mails are delivered just fine.

    So, what is the problem with MailScanner and Postfix. I'm not a big fan of amavis and I wish to change it.

    No problems in logs.

    I found the problem and fixed it (sort of). It was caused by mailscanner version and some incompatibility with postfix. I used the debug mode in mailscanner and then fixed the problem by using Postfix.pm from latest version of mailscanner.

    Now the system works just fine.
