I installed SpamSieve, and all was going well, and it was working perfectly. Now nearly all mail arrives ‘opened’, and spam filters don’t appear to be working. The only thing I have done in the interim, is open Mail on my other computer (I run two offices) which does not run SpamSieve. I have since closed Mail on that computer, but the computer is still on. Not quite sure what to do. I presume because all email is arriving ‘opened’ it is not being filtered?
