Topic: IMAP UID's and outlook

[John Quirk]

Hi we have server 5.2 running as a mail sever and firewall. We recently moved all our users over to the IMAP procol and win98 roaming profiles. After we did this we started to get errors from out look complainging that UID's where out of sequence
and that it was an imap problem. Of course I don't trust MS error messages but it
seems we may have misconfigured something. The roaming profiles are controlled
by a another box running redhat 7.2 and samba. Has anyone got any suggestions
as to what my be causing this?
I have not add the procmail feature that other users report that seems to start this off.
Thanks

I believe in this case Outlook is correct and the UIDs are out of order. If you try IMP you will find a similar problem: it tells you how many messages there should be, but it only lists those messages up to the first message that is out-of-sequence. It doesn't give any error, but it doesn't display all the messages either.

I am not too sure what the mechanism is that causes this, but I got around it by moving all my mail files from the 'cur' directory of each user's mailbox into the 'new' directory. This seemed to allow the IMAP server to reissue UIDs and it all worked from there. Users mailboxes are in the user's home directory and each has a cur/new/tmp sub-directory.

A slight problem with that though: message delivery dates all got changed to the current date, but at least I got my mail back.
