288579 - Thunderbird does not properly retrieve mail due t onot playing nice with Norton Anti Virus

Status: RESOLVED DUPLICATE of bug 288578

(Thunderbird :: General, defect)

Description

[Howard Kaikow]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.6) Gecko/20050317 Firefox/1.0.2
Build Identifier: Thunderbird 1.0.2

In February, I posted the thread "Cannot download messages with attachments, at
least not all" (see  http://forums.mozillazine.org/viewtopic.php?p=1355242#1355242).

Less than an hour ago, I discovered the cause of the problem.

Thunderbird is not playing nice with NAV 2004 and NAV 2003 when incoming
emailscanning is enabled.

Reproducible: Always

Steps to Reproduce:
1.Enable Incoming email scanning in NAV 2004 0r 2003 (don't know whether problem
exists with NAV 2005).
2. Send yourself a message with an attached .zip file. It has to be  of some
size to force the problem. You could try using my file at
http://www.standards.com/Sorting/SortPerformance.zip.


Actual Results:  
Thunderbird announces that there are N messages to receive.

If the message containg the .zip is say message 5, THunderbird will do thr
following:

1. Messages 1-4 will be downloaded, but will not be deleted from the mail server.
2. Messages 6-N will no be downloaded until message 5 is removed from the mail
server.
3. The pop up window announcing how many messages have been received does not
appear.

Expected Results:  
All N messuges should have been downloaded and deleted from the mail server.
The pop up window announcing the number of received messages should appear.

I'm using NAV 2004 with all program updates and virus definitions as of 31 March
2005.

If I disable NAV's incoming email scanning, there is no problem receiving the
messages wit hsuch attachements.

Note that the problem does not occur with smallish .zips even when NAV's email
scanning is enabled, so message size is also a factor. Likely a timing issue
while NAV vets the message.

Note that I also pasted 356KB of text into a message body. No problem receiving
that message, likely because NAV did not have to mess around with unpacking an
attachment.

It would appear that Thunderbird and NAV are not playing nice whilst NAV is
examining the message containing the .zip attachment.

I would guess that somebody at Mozilla has contacts at Symantec, or vice versa.

Note that other mail programs, e.g., Eudora 6.0.3.0 and Outlook Express 6, do
play nice with NAV 2004.
So the problem could be caused either by Thunderbird or NAV.

 I found a workaround.

In NAV, one can select the option "Protect against timeouts".

From the NAV Help.

"Timeout protection places hidden text at the top of your email messages. Your
email program should remove this text. If you see NAV Timeout Protection in your
email messages, you can ignore it"

Thunderbird should remove that text.

I've used Eudora for years withiout using that NAV option, so I guess
Thunderbird's handling of timeouts could be improved.
