(Note: I am aware that SME 10.1 is EOL, however there is no alternative for me for the time being).
We have a 10.1 SME box, minimal contribs (fail2ban basically). Today a user complained about not receiving email from a certain sender. Upon closer inspection, email
was flagged as spam, but spam score did not exceed the spam threshold, so it was delivered to the queue.
However nothing appeared on the email client (thunderbird / POP-3) of the user. Checking the user's home directory it seems as though SPAM-marked messages ended under ~user/Maildir/.junkmail/new which, if I understand correctly, is a Horde thing.
I have to move all .junkmail residing messages to the respective ~user/Maildir/new (inbox) directory, however there are more than 100 mailboxes, so basically I'm afraid I might bork something here.
This behaviour seemed to have started some time before
June 15th. What might have been installed at that time that modified SME behaviour this way? And more importantly, is it fixable? We have a large volume of mail messages and a lot of them are serious ones, having legal consequences.
Thanks in advance for any help provided!
