    hi i followed this Virtual Users And Domains With Postfix, Courier And MySQL (CentOS 5.1).

    In outlook i can login to the accounts. when i do test mail account i can both login and send a testmail.

    However on the mail server i cannot recieve the test email.

    If i send mail between the email clients and the local linux accounts the server can recieve them. However once i send from somewhere like gmail, there is no email being recieved, in gmail i do not get an email delievery messege daemon saying that the account does not exits.

    What i suspect is the spamassasin is overactively destroying the mails. In the emails that i send via the server email accounts but not the linux accounts there is ***SPAM*** inside the top header.

    Here is a log when i send a test mail through outlook

    if it really is a hyper active spamclient how do i reduce its settings while still stopping spam?

    Further information mailer daemon just got back from google:

    log_level: 3
    mech_list: PLAIN LOGIN
