User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en-US; rv:1.0.1) Gecko/20020823 Netscape/7.0
Build Identifier: 20020826 

When using Mozilla mail 1 day after using netscape mail against the same IMAP
mail server, Mozilla deletes the trash folder and starts with a blank one.


Reproducible: Always

Steps to Reproduce:
1. Run Netscape 4.79 at work and delete some mail into the Trash
2. Run Mozilla 1.1 from home against the same mail folder
3. Click on IMAP Trash folder.  List shows 0 entries
4. Delete some mail.  Mozilla starts trash again at 1 entry

Actual Results:  
Trash silently was deleted by Mozilla

Expected Results:  
Trash mailbox should be maintained across multiples runs of Mozilla/Netscape 4
over multiple days.

Mozilla should never silently deletel mail.

Appears to be similar with Mozilla for Solaris.

Using both on the same day does not appear to cause the problem. Only after a
day rollover.

Jim, are you sure you have both Netscape 4 and Mozilla configured to move
deleted messages to the Trash for that account?

Yes.  Both are configured for move messages to trash upon deletion.  Both
succesfully move message to trash, but in the case of Mozilla, the first message
moved to the trash one day after Netscape accessed it causes silent deletion of
the Trash file.  I've confirmed this with ls -l showing a size of zero.

When I go back to work and click on Trash folder, I get a message from Netscape
4 to the effect of "Mailbox shrunk from size xxxx bytes to zero bytes."

FYI. IMAP Mail server info.

Solstice (tm) Internet Mail Server (tm) 2.0p12 IMAP4 service 

(Yes I know it's ancient.)

WorksForMe using FizzillaCFM/2002083017 on 10.1.5 and Netscape Communicator 4.8.

Could it be the old IMAP server that we're using is not reponsding to requests

What kind of mail conversation trace would be most helpful?  tcpdump on OS X?

Jim, I'd suggest testing using another IMAP server, such as a free trial

I was unable to reproduce this problem using the .mac IMAP mail service.  I
guess we'll have to chalk it up to nastiness involving Netscape 4 and SIMS 2.

This problem also occurs when using Netscape 7 (Solaris) at work and
Mozilla/Netscape 7 at home.  Problem seems to be that Mozilla updates the Trash
header only when you click to view that folder.  In this case the X-IMAP line
indicates 41 messages in the trash.

Problem occurs when I leave Mozilla running at one site overnight.  It's
checking for mail automatically and filtering some items to the trash.  There
are items in the trash but the X-IMAP line has not been updated.

I log in from home the next morning (while Moz is still running at work) and Moz
at home must be confused about the trash because the first time it puts
something in, it (or the IMAP server) deletes the trash.  Moz then reports
"Mailbox shrunk from xxxx bytes to 0 bytes."

Help me a little bit here.  Should an IMAP server support concurrent access to
multiple mailboxes?  Why does this only occur with Trash and not with Sent?  My
Sent box is also accessed from both sites and has never been deleted.  What is
the proper behavior of the IMAP server in this case?

Turns out that our IT Nazis have a cron job that every night cats /dev/null into
HOME/Trash, Mail/Trash and .dt/Trash. .

Please feel free to close this bug.  Sorry for the trouble.
