Hello! I have a nice working postfix/dovecot server that I've been using with no problems for a couple of years, Centos 6.2, mail version 2.6.6. I'm now using smtplib inside a Python script to send emails directly to my local network and in all messages the sender is being switched to user uid 502 (spamfilter).
These lines appear when trying to send from 'craigallison' for instance. Feb 1 13:54:53 mercury postfix/pickup[21186]: 41D41C090F: uid=502 from=<craigalli...@mydomain.com> I can provide further info if required, I've search everywhere for possible reasons and am stumped. Have tried using authentication for the user but makes no difference. Thanks Craig Craig Allison
