Lately some of the emails I get from a particular website have started going into my Junk folder. I have the sender address in my Contacts, and in Mail's Junk Mail preferences I have the box "Sender of message is in my Contacts" checked. Yet this doesn't seem to be working, they're still being filtered. The site is an online forum, and it emails new postings in threads I've subscribed to.
I also had the option "Perform custom actions" selected. I think this may have been left over from years ago when I was also using a third-party spam filtering plugin. When I look in the "Advanced..." page, the conditions are equivalent to all the checkboxes on the main screen. I tried changing that option to "Move it to the Junk mailbox", but this actually made things worse -- instead of just a couple of the messages being moved to Junk, almost all of them were -- so I put it back.
I haven't figured out what might be distinguishing the messages that are being marked as junk.
Any idea why that option isn't really exempting them from junk filtering?
In case it's relevant, I also have a rule that matches these messages; it matched the sender and subject line. It was just marking them as read (I have a menulet that shows the number of unread messages, and I don't want these included). When the messages were put in Junk, they were still marked as unread, so this must be happening before rule processing. I tried changing the filter to move them to a new folder, it didn't help.
