105805 - MS Exchange IMAP: File->Send Page message cannot be saved in SSL IMAP folder with MS Exchange 2k

Status: VERIFIED WORKSFORME

(MailNews Core :: Networking: IMAP, defect)

Description

[Lorenzo Colitti]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Win 9x 4.90; en-US; rv:0.9.5) Gecko/20011011
BuildID:    2001101117

When using File->Send page, Mozilla hangs forever when trying to save the
message to an IMAP folder on a MS Exchange 2k server. This means that the
message cannot be copied to the Sent folder or to the Drafts folder and that it
is lost forever.

Mail must be restarted for any further communication with the server to take place.

Reproducible: Always
Steps to Reproduce:
1. Set mozilla to use an IMAP mail server and to copy sent messages to the Sent
folder on the server.
2. Open a page (I used http://www.theregister.co.uk/content/4/22354.html)
3. Click File->Send Page
4. Send the message
5. Kiss the message goodbye :)

Actual Results:  Mozilla sends the message correctly but "hangs forever" trying
to copy the message to the Sent folder.

Expected Results:  Mozilla should copy the message to the Sent folder.

By sniffing the wire I can see that Exchange is closing the IMAP connection with
a RST when Mozilla finishes sending the message; this might be Exchange's fault,
but Mozilla does not complain or warn the user, it just sits there forever.

If the Cancel is clicked the message still can't be saved on the server, in the
Drafts folder or anywhere else, because the IMAP connection is gone and Mozilla
doesn't notice.

I am not using the Exchange SMTP server, just the IMAP server.

This is using a secure connection BTW. I don't know if it happens without SSL.

dup of bug 100353?

Comment 5

[Lorenzo Colitti]

In bug 100353 the operation was very slow because of problems in the IMAP code,
but here I am seeing it fail completely because the server drops the connection
and mozilla doesn't notice. This seems to point to a protocol problem rather
than a code problem.

Also, bug 100353 happened only on Macs, whereas this one hits both WinME and Linux.

Much to my surprise the problem only comes up if using SSL. This means I cannot
use a sniffer to debug the problem. :-(

Reporter, can you please retest with RC1

No longer seeing this in 1.0 RC1.(I think it went away somewhere between 0.9.9
and RC1). Marking WORKSFORME.

However I still have problems in saving attachments from MS Exchange 2000 via
IMAP over SSL. I will file a new bug for this behaviour.
