    Hi all
    I discovered today a strange behavior on one of my servers.
    Several IPs were able to connect to PostFix and send emails using SASL authentication.
    I thought first the account used has been compromised so I changed password using ISPConfig but connections spammers could still connect and send emails.
    So I deleted the account and messages continued to send through.
    Mail log is full of
    postfix/smtpd[21107]: 33BC02A4F1:[], sasl_method=LOGIN, [email protected] where [email protected] is a non existent email (I checked in database).
    At this moment, the only way to stop sending have been to disable LOGIN method for SASL.

    Any idea haw such a thing can happen ? I googled my problem but found no solution…

    Thanks for your help

    I got the same error 3 month ago…
    The solution was to reconfigure the service with ispconfig…
    From then everything work fine ;-)
