I’m using the trial version of SpamSieve and really am considering to buy it, since it’s already catching most of my spam messages after only a few days.
The only problem I’ve got is when I use it with the IMAP-Account that is running SpamAssassin. I’ve manually added a blacklist rule that tells SpamSieve to block every message that contains “Spam detection software, running on the system”. The rule works fine, if I manually apply rules in AppleMail (control-apple-l), but it doesn’t work when it runs the rules automatically every time I get mail. The SpamSieve rule is already on top of the other rules. Have you got an idea what I could do?
