[MlMt] message keep reappearing in junk

[Robert Brenstein]

Ok. I have been checking past few days and confirmed that indeed the 
problem is caused by having MM with SpamSieve on 2 computers. Moving 
certain messages out of the junk on one computer makes them reappear 
there if they are classified as junk on another computer later on. The 
junk flag is not transferred, that is messages reappear in the Junk 
mailbox but there are still non-junk. The problem is that whitelisting 
is way behind on the computer which I do not use regularly, which is the 
implicit source of the issue. Now that I understand the cause of the 
behavior, I can deal with it.

I haven’t experimented with the $NotJunk keyword yet, as suggested 
below.

I'm thinking that the problem is somehow related to having MailMate 
running on two machines. Here's something to consider:

Every time one instance of MailMate moves a message to the INBOX then 
the other instance of MailMate is going to see it as a new message. This 
is simply how IMAP works. If you are running SpamSieve on multiple 
machines then this could be a problem. To avoid this problem then 
MailMate, by default, does not apply SpamSieve to any message with the 
“Not Junk” (`$NotJunk`) keyword -- *and* this keyword is applied to 
anything moved out of junk.

This should make it work except for the special case where the IMAP 
server does not allow/support setting the `$NotJunk` keyword. This 
should be rare, but I think this might include Exchange IMAP (which has 
little support for custom IMAP keywords). Is it an Exchange IMAP server?
