    Can you guys take a look at this Postfix log?

    Code:
    Oct  8 08:28:33 core postfix/smtpd[9137]: 9CB614AB54B: client=static-200-105-156-170.acelerate.net[200.105.156.170]

    Oct  8 08:28:35 core postfix/qmgr[2352]: 9CB614AB54B: removed
    My mail server's not an open relay.

    Can this be classifed as backscatter? I've never seen this one before.

    Is one of those email addresses located on your system?

    I don't see that address in the log, only advertising-livewhenready.com@core.200-paul-sf-ca.livewhenready.com

    Basic question, is your mail server checking spf?

    Cheers

    As far as I read the log, a email for the local (virtual) address has been received and then delivered to the local system user advertising-livewhenready.com. The recipient
    Code:
    advertising-livewhenready.com@core.200-paul-sf-ca.livewhenready.com
    means not a real email address in the case that core.200-paul-sf-ca.livewhenready.com is the hostname of the local server and advertising-livewhenready.com is the name of a user in /etc/passwd
