In my tests, I see Strato reports the new Seen status twice:
C: A006 UID FETCH 5 BODY[1]
S: * 5 FETCH (FLAGS (\Seen) UID 5)
S: * 5 FETCH (FLAGS (\Seen) UID 5)
S: * 5 FETCH (BODY[1] {174}
S: <snip>
S: UID 5)
S: A006 OK FETCH complete
Although I've heard of no other IMAP server that does this, I think
this is in fact legal. The IMAP server is allowed to send unsolicited
responses such as in this case where the client request has caused the
message flags to change.
However, it's probably not good that they send the same thing twice,
and the behavior is erratic -- I couldn't cause it to happen again by
simply setting the message as unread. And again, no one else has
reported an IMAP server that exhibits this behavior.
But, technically, it seems "legal", so...

Right - the message flags didn't change.
I made two changes in our code repository that should correct this
matter. Since the code handles IMAP server responses, it'd be REALLY
GOOD if EVERYONE could TEST these changes.
PLEASE download a SquirrelMail 1.4.23 snapshot from our downloads page
and let us know if you see any problems, even if this issue doesn't
apply to you. The snapshots on our downloads page already contain
these fixes - you do not need to wait to test this. (Or pull from our
SVN directly.)
Thanks,
Paul
