134697 - email corrupted by filters set up to move certain message to Local Folders

Status: VERIFIED DUPLICATE of bug 136636

(MailNews Core :: Filters, defect)

Description

[Mark Mercer]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:0.9.9) Gecko/20020311
BuildID:    2002031104

I set up a number of filters based on various Sender and Subject criteria (most
with at least 5-10 conditions in the rule), in one of my POP3 accounts. These
rules are to move specific messages (such as travel deals from hilton.com,
delta.com etc.) into specific folder (such as my "Travel" folder). Because I
want all my subject-specific folders to be the same regardless of which account
received the mail, I set up the destination for the move as folders inside my
"Local Folders" rather than  separate "Travel" folders, one for each POP3
address. Although for now I only have the rules set up in one mailbox, I plan to
duplicate them for other accounts, so I want their destinations not to be
account-specific.

When the rules fire on incoming mail, often (but not always) the moved mail, and
remaining emails in the account's inbox, are corrupted by having missing
headers, or partial text, or text from the wrong message. It seems like mozilla
is cutting out the wrong block of text from the mailbox file when it moves the
message, thus corrupting the message that triggered the file, and/or the
messages before or after it remaining in the inbox. 


Reproducible: Sometimes
Steps to Reproduce:
1. Set up filters in a particular account mailbox, to move, let's say, all
messages with sender contains hilton.com, into a "Travel" folder that is in your
"Local Folders" rather than in the account's mailbox.
2. Receive mail from that destination. (sign up for travel deals opt-in mail at
that site, for example. No reason a test message matching your filter wouldn't
work instead.)
3. Look at the message after it's automatically moved to your "Travel" (or
whatever) folder in Local Folders. Often it will be corrupted by missing
headers, missing text.
4. Look at the message that was in sequence just before and/or just after it,
still in the inbox for that account. One or both of those may be corrupt,
contain part of what should be the moved message, or nothing.

Actual Results:  Sometimes works cleanly, often corrupts as described.

Expected Results:  Properly moved the message which triggered the filter,
without corrupting any headers or text in that message nor in surrounding messages.

We have had quite a few bug reports regarding mismatch body/hdr on filtering of 
local mail but we haven't been able to reproduce it.

confirming this one so that it stays in the radar.

I just downloaded the latest mozilla build for win32 and am still seeing this 
problem as well. I am running under Win 2000- 

the filters I am seeing get mixed up are those looking for

sender   contains    text

with the result being moving to different folders.
I am seeing very much what the person who assigned the bug describes- that
when I go look at the folders, the mail has been routed as expected (based on
the subject) but when I try to open the message it contains text from a
different message - sometimes from multiple messages- and header information
printed in the message. 

 I have about 10 filters- most based on subject contains text... some with
the result being move to a folder, some with the result being delete. I also have
one filter based on the to/cc message. 

This screams of being a memory leak..  please fix

Correction to my recent addition- the filters are not consistently putting mail
where they are supposed to... It looked like they were previosly , but after
letting them run a couple of hours, I see that the "sender contains" filters 
are indeed getting confused on this level as well.

Can you try reproducing this bug again because a related corruption bug 122361
has been fixed in latest nightly builds.

[Mark Mercer]

Tried the 2002040803 build, and send myself about a dozen messages that matched
my Subject filters. All got filtered ok. But haven't seen the bug in the 0.9.9
milestone for a few days either; it's quite intermittent. Will continue to test
the nightly. Bug 122361 does sound very similar - same symptoms, so if that's
fixed maybe we're ok.

Got problem again on the 2002041003 build. A message came in that met the
criteria to get filtered to a local folder. That message had three attachments
in it. The What arrived in the destination of the filter was the complete
message, the 3 attachments, and the start of the next message from my inbox. 

Remaining inbox messages from that download of POP3 email were corrupted - wrong
message entirely in one, partial or no messages in other.

I would dup this bug also. If you see the bug again after bug 136636 has been
fixed, reopen it.
