Hi Zhang,
Thanks for your reply. No, I have no record of modifying any Amavisd or Spam Assassin settings from their originals. Amavisd was new to me so I didn't have a reason to think I had a better way to configure it, and likewise I've generally been fine with letting Spam Assassin run as-is.
OK, so in order to test one item at a time I'm going to modify the following configuration block in /etc/amavisd/amavisd.conf by un-commenting one line at a time:
# don't perform spam/virus/header check.
#bypass_spam_checks_maps => [1],
#bypass_virus_checks_maps => [1],
#bypass_header_checks_maps => [1],
Right?
And because this is in the "MYUSERS" section this will apply only to outgoing email, correct? If I want to try the same for incoming email, where do I find that configuration?
And since it's the weekend now, I'll need to wait until Monday because the traffic goes way down on the weekends and isn't a problem.
