GMail IMAP/Junk FIlter issue

[Tyrenta]

I posted this in response to an earlier IMAP issue, but I don't see it in
todays threads so I'm reposting with a new thread -- apologies if I'm double
posting somehow:

Passing along another Gmail IMAP issue i ran into that was pretty
significant:

I also had some performance/speed issues when syncing, and may have solved
them but have not yet had a chance to see if they were fully resolved by the
below:

I have a Gmail groups Admin account I set up with IMAP access in WLM -- this
account thus receives overflow of all mail sent to the domain where an
account does not exist.

I immediately noticed the Junk Mail folder was very large, growing quickly,
and my PC slowed to a crawl. I finally figured out the issue:
- the junk mail filter was accumulating mail at a rate of several per second
(i.e. thousands per day), and also adding these into my Gmail account online
with the 'Junk Mail' tag
- these were all spam, sent as I mentioned to addresses in my domain that
did not exist
- I determined that somehow the Junk Mail filter was processing mails before
Gmail's system had a chance to; it seems perhaps Gmail has a 'pre-spam'
filter of sorts
- Turning off the Junk mail filter solved the problem -- these mails stopped
accumulating in WLM, stopped appearing as tagged 'Junk Mail' in GMail, and
most interesting, also did not appear in Gmail's Spam folder

while this seemed to solve both the accumulation of so much spam, as well as
the performance issue in general (both PC performance and folder syncing), I
now have no junk filter on any of my other pop accounts.

Its a clear workaround, but it would be made easier if you could apply the
Junk filter on an account by account basis.

new thread.
Both were posted using the web CDO interface.

The alternative, setup this newsgroup in an nntp newsreader client. e.g.
Windows Live Mail
news://msnews.microsoft.com/microsoft.public.windows.live.mail.desktop


How is is possible that a local email client processed Gmail in advance of
Gmail server/filters ?

Yes I realized it was because that interface I used did not show
recent posts, only the dates the thread was started.

I don't know, but it does. It not hard to recreate, just turn the Junk
Filter back on. Again this was for an Admin account on Google Groups
that also receives copies of mail addressed to non-existant accounts,
so it was somehow picking that up with the junk filter. These mails
did not however make it to the admin account inbox or spam folder
using the gmail interface, so I can only assume there is some
additional filtering going on behind the scenes that is not visible
normally. There were literally thousands of mails being processed in a
very short time frame......
