Thanks for this tip. I didn't know that it's possible to stop Courier MTA rewriting those mails. > I use Courier as well and SA works great for me.

Maybe because of security issues. Since my server serves very few users, I see no resource problems in using spamassassin instead of spamc/spamd. But could using spamc/spamd resolve the locking problem I described? > [...] > If you have any specific questions about interfacing SA with Courier, > I'll be glad to help out. Thanks a lot!
