328417 - Offline should use junk mail download when appropriate

Status: RESOLVED WORKSFORME

It seems to me that the junk mail filter downloads the body of new messages to see if they might be junk. I have my Inbox set to be available offline (using the offline extension). When I go offline, the offline extension goes and downloads all mails again. If the junk mail filtering has already downloaded the mail, it would be good for the offline extension to store the messages for offline use when they are downloaded during junk mail processing.

Reproducible: Always

Steps to Reproduce:
1. Install offline extension, make Inbox available for offline use, and activate the junk mail filter.
2. Check for new messages. The junk mail filter will quietly download the messages in the background, and mark the spam as spam.
3. Go offline. 

Actual Results:  
The offline extension will download the same messages AGAIN, for use offline.

Expected Results:  
When the junk mail filter downloads the messages, they should be stored by the offline extension, so that they do not need to be downloaded again. This applies only to messages where the junk mail filter actually does download the whole thing.

I have a $50 paypal bounty on this. The bug is also registered in Launchpad at https://launchpad.net/malone/bugs/32625

should this be higher severity, or ENH?

Comment 2

[Kent James (:rkent)]

It would be good to verify that this still occurs, as it is a fairly old report. But I would call this a bug, not an enhancement - but a minor bug.

T-bird seems to download the full message body as soon as the new mail arrives, but perhaps that's just an illusion because I am mostly using high speed networks these days.  Do we know if an explicit change has been made?

I attempted to verify if this is still occurring, but I suspect that I will need to find a very large attachment (as I also suspect that attachment size will not be factored into filtering for junk) and my connection is simply too fast to gauge if this is still occurring or not.

Windows 7 Ultimate 64bit (RTM) and Tb 3.0b4, Shredder 3.0pre, and Shredder 3.1a1 - mail profile contains several email addresses from various free sites as well as my ISP, mixture of IMAP and POP (and Yahoo via simulated POP via WebMail extension).

Mark, do you still see this problem??

After version 3, if this happens at all this would only happen if autosync were disabled, which is not the default

I don't see this any more. Since I offered a bounty I am happy to pay up! I love the idea of corresponding about a decade-old issue, thanks to everyone who keeps Thunderbird my favourite mail client :)
