Morning ALUGers! I've got an interesting one with false positives in SpamAssassin and I'm hoping someone here might have used or even had the same problem.
I have a client who runs a precision instrument business for the scientific industry. They have a number of clients out in Japan and legitimate e-mails from them are being flagged as spam.
Our default score for spam is 4 and these messages are coming in ranked at 4.495, hence they are being flagged as spam. I'd be happy to change the setting to mark all messages with a score higher than 5 as spam for this client, but that wouldn't stop a small number of spam messages (10) I've received today alone in my own Inbox.
We have identified some phrases we believe might be causing the high ranking but I don't actually know how to train SA that these phrases are ok and shouldn't be marked as spam. Apart from increasing (or is it decreasing) the spam ranking for the clients domain to 5, I can't see a way around this.
Any suggestions?
Nick
