This might be a tad off topic, but I got a few strange lines in the maillog and I wanted another opinion and could think of no better place to ask.
Does this look like an attack or a probe looking for an open relay... or do you think its just badly formatted mail? I find it strange and a little amusing. courieresmtpd: error,relay=::ffff:66.169.236.188,msg="554 Syntax error - your mail software violates RFC 821.",cmd: MAIL FROM: [EMAIL PROTECTED] courieresmtpd: error,relay=::ffff:66.169.236.188,msg="502 ESMTP command error",cmd: RCPT TO: [EMAIL PROTECTED] courieresmtpd: error,relay=::ffff:66.169.236.188,msg="502 ESMTP command error",cmd: DATA courieresmtpd: error,relay=::ffff:66.169.236.188,msg="502 ESMTP command error",cmd: SUBJECT: Anti-Relay Notification. courieresmtpd: error,relay=::ffff:66.169.236.188,msg="502 ESMTP command error",cmd: ATTENTION OWNER OF MAIL SERVER:. courieresmtpd: writev: Connection reset by peer Before you ask, no, this machine is not an open relay and never has been :) Also, pacbell.net is obviously(?) not a local domain of mine.
