Darin,
We're doing the same/similar thing. We have a newsletter subscription
application for an elected official. Question for you: Out of about
10K
addresses, we're getting about 1,000 bouncing. After checking those
addresses individually, there are less than maybe 10 that are actually
bad addresses.
1) Addresses are good.
2) Mail comes from [EMAIL PROTECTED]
3) Mail bounces to [EMAIL PROTECTED]
4) If I login as [EMAIL PROTECTED] and send a message to the destination
email, it goes through just fine.
5) If I use ASP CDO to login as [EMAIL PROTECTED] and send the message
to destination email, it gets bounced.
Header for bounced email using CDO (domains, ips, and emails changed):
===================================================================
Delivery failed 3 attempts: [EMAIL PROTECTED]
Original message follows.

Do some SPAM filters require a "Reply-To" header? It's definitely
not the content of the email. We can send those individually without
any problems.
Any ideas or suggestions would be greatly appreciated.
Incidentally, for us, it takes roughly 2 hours to go through the first
7K-8K of the recipients. For some reason (I'm guessing bounces), the
last 2K-3K take about 4 hours to clear the queue.
1GHz/512MB RAM - bandwidth for email throttled to 256kbps
avg email size 17K
Thanks,
Norm

No, it's a unique message body to every recipient...separate SMTP
sessions
for each recipient...it's a true newsletter subscription system.
However,
it is multi-threaded....usually runs about 10 simultaneous threads.
Even at
that, it's still 10 times faster on average than the benchmark of 10
seconds
per. I think total message throughput answers the original question
more
completely.
Darin.
