210716 - "Empty" mails using IMAP

Status: RESOLVED DUPLICATE of bug 249195

(MailNews Core :: Networking: IMAP, defect)

Description

[Samuel]

User-Agent:       Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:1.4b) Gecko/20030516 Mozilla Firebird/0.6

We're using an IMAP server and we have very often problems opening emails with
Mozilla. The problem is that after working with mail for a while the content of
many emails is no longer shown.

This becomes a major problem when we try to move emails from IMAP to a local
folder since the email content is not being copied! (but the mail is being
deleted from IMAP anyway) When I look into my local folder these emails have

* no title, no sender, no content
* they're dated to 01.01.1970

When I view the message source it says something like:

From - Wed Jun 25 14:27:21 2003
X-Mozilla-Status: 0011
X-Mozilla-Status2: 00000000

This happens with all Mozilla Mail versions that I've tried out so far (1.0,
1.3, 1.4, Thunderbird) and it happens on all our machines (NT4).

*Approximately 20-30 percent of the emails moved are affected by this problem.*

All this works fine with MS Outlook so we believe that it's not an IMAP server
problem.

Reproducible: Sometimes

Steps to Reproduce:
1. Move mails from IMAP to local folders.

Actual Results:  
Many emails are lost (the content was gone).

Expected Results:  
Move the mail.

are you using the UW IMAP server that comes with Redhat? I suspect this is an
IMAP server behaviour exposing a bug in Mozilla - that IMAP server rolls UID
validity a LOT and we don't invalidate our memory cache when that happens.
However, that usually causes mis-matched messages, not empty messages.

Can you attach an imap protocol log by following these instructions?

thx.

without an imap protocol log, I can't really know what's going on. (Did you send
me one already privately?).

I have the same problem. I tried to generate the IMAP log as instructed but
found nothing unusual. I even turn on the log on the IMAP server and apparently,
Mozilla did send an empty mail to be copy over to the server.

This also happened sometimes when you move large amount of mails from one folder
to another so it might not be restricted to IMAP.

what version of thunderbird/seamonkey are you using? Do you have the folder
configured for offline use? There are several fixes in the latest builds that
might help.
