We have SBS 2003 fully patched, and Outlook 2003 as our client.

To allow marketing to send Bulk emails, I do no go through our
Exchange server, as the ISP will not support the volumes (we send
customized individual Emails created by Email-Merge in Office).

In addition, for legacy reasons, our inbound Email (POP3 boxes) and
corporate website is hosted at a DIFFERENT ISP. This has caused
increasing issues with spam filters as our outbound IP (office
external) is way different than our MX inbound IP (Other ISP, and
Website).

So, I have been attempting to simply generate the personalized bulk
emails here and transfer them to the other ISP using IMAP, and now
POP3 protocols. In this way, the outbound and inbound IP addresses
are the same ISP, and same as our site, so the spam filters let it
all go through, and the only rejections we get are real ones.

I have set up the profile(s), and and on the Tools | Options | Mail
Setup tab, have cleared the tickbox for send mail immediately, and
changed the auto send/receive times to 10 minutes, the theory being
that we can generate them at ~ 1 piece per second, and then every 10
minutes, outlook would log in to the other ISP and dump all the
outbox mail into the outbound mail servere there.

Theory was good, but what's happening is (based on Outlook Logs):

Outlook is Logging in for each and every individual piece of mail.
Outlook send the current mail piece, then goes in to an 'idle loop'
for approx 5-6 seconds, meaning we get a throughput of ~ 8 per
minute, which is unacceptable with our 6000 piece monthly
newsletters, etc.

So, my question is, can anyone tell me the registry setting to reduce
this idle loop, or better yet, how can I fordce it to simply transfer
the entire contents of the Outbox to our ISP in a single Login - my
ideal would be for outlook to wake up every 10-15 minutes, log in to
the external ISP, transfer all the mail in the outbox, the logout and
wait anotehr 10-15 min. If I can get that to wor, I can play with
the Bulk generation counts and time periods such that the smaller
batches can go out in one hit, and the larger ones broken into a
manageable number of portions??

My opinion is that you'd be better off hiring a fulfillment house to do your
mass mailing.
