I see. I already skimmed through one of the IMAP RFCs but was not
sure after reading it whether the FLAGS are also to be expected
after SEARCH and SORT commands.

I already prepared a patch for squirrelmail that fixes their bug, I
will send it to the developers a soon as it has been tested

The strange thing is that I definitely didn't use another client at
the same time. I even replicated our production server in a vmware
and tried the same sequence with a single telnet session which still
produced those flags the first time after I have logged in. Another
strange thing is that the same FLAGS responses get repeated for the
same messages ( see ids 307, 381, 971 in my original post ), that is
only a minor issue though.
I moved a lot of mails from another imap account to the one i get the
flags with, maybe something went wrong with the maildir while moving
those messages. As soon as I have time I will compile a debug
version, attach to the imap process and step through the code to see

As long as no proprietary clients have troubles with this I wouldn't
add a workaround. If other open source clients have problems with
that, they should be fixed as well. I will see if I can find someone
who can test with outlook and evolution and check how those clients
