4.5 IMAP changes? Nokia E61/E62 can't get mail body

Something must have changed with the way IMAP messages are handled WRT the client for the IMAP client to get so confused. No clue, but consistent behavior from 3 different Nokia E62's that were great with 4.0.x but choked with 4.5.0.

I'm guessing this is related to my other thread about Mail For Exchange getting confused also (http://www.zimbra.com/forums/showthread.php?t=6348).

Anyway, all is good!

Hmm, well, this problem is back for me on my E62. So definitely something is still not right.

It is not practical to keep deleting and re-adding the imap account settings. PITA.

There were some code changes in 4.5 that require a full resync, have you tried doing Options->Full resync on your E61?

Full resync worked fine for Nokia Mail for Exchange (zimbra mobile). This problem is strictly for straight IMAP.

The only sort-of fix is deleting and re-adding the IMAP account which seems to only be a temporary fix as I am again getting the same problem.

Thanks very much for the dump. It shows that the 4.5 IMAP server is misbehaving badly when it comes to UID SEARCH. I'll fix this ASAP and try to have it in 4.5.1.

Actually, I'm wrong. UID SEARCH is fine. Still need to get to the bottom of this.

This dump looks completely fine. All I see is the client visiting each folder in turn, then returning to the INBOX and doing an IDLE. The only difference from 4.0.5 is that we've reenabled the IDLE command...

Should I try one of the account switches to elicit possibly different behavior, like account/tb (thunderbird)?

BTW, are those account switches documented anywhere as to what exactly they do and which ones are available?

I doubt any of the "account switches" would help here. We need some sort of repro case. Our QA folks will try to work on it as soon as possible, but input from folks seeing the issue is welcome.

From reading your the forums, it would seem that you have some Zimbra employees who use E61's. I'm sure they are using MFE.

One thing to caution is don't use MFE and IMAP from the same server to try and test/repro this. It will lockup the phone (did for me)

I did use MFE and IMAP on my E62 to 2 different zimbra servers with ZCS 4.0.5 without problem.

Is there any progress to resolve this problem? We updated to the latest 4.5.3 release but our E60 won't do imap as expected.

If you look at the posts from dkarp above the QA at Zimbra are having a problem reproducing this issue. I would also bet that there's no bugzilla entry for this (although I haven't read the whole thread), if you can produce some evidence/diagnostics of the problem then file a bug entry and it will get looked at.
