Hello, I just went into some problems with spam scanning. I do not know whether it's really related on my upgrade of spamassassin to v3.1.8, but I saw the issue at the same time.
The problem is that mails are altered after using an ACL with spam scanning. I am not using the old demime method. There is a carriage return that is added between the message and the attachments. That means signed mails fail validation because the message has been altered. It does not cause any problem with unsigned mails or encrypted mails however. I don't see any reason why spamassassin should modify the mail if called from the ACLs. But after I removed the "spam= nobody:true" in the ACLs, the problem stopped.
