Email keeps bouncing and costing thousands of dollars per mb

[sarahleehill]

We are running W2k Server with Exchange 2000 and have a major problem with sending email to other users who have small mailbox limits. We also have email set up to forward to other accounts. When we send email we are not receiving an undeliverable confirmation right away and our exchange server keeps trying to send or forward the email as per the defaults in SMTP Virtual Server (Delivery Options). Even if we do receive an undeliverable; Exchange is set to forward all mail and therefore then forwards the undeliverable creating a never ending cycle until we delete the messages.
Therefore it keeps trying to send the email every 10 minutes for 3 tries and then every 15mins for about 12 hours and then we receive a delay notification.
Every time the mail bounces we use up precious Mb's and get charged for this. What would the best practices be for configuing the SMTP Virtual Server Delivery Options to stop this. Or can we solve this problem another way.

Thousands of dollars per MB? Better change ISP ;-)

If you don't want it to happen, you're only option is the most obvious one, turn off the re-sending.

if you are charged by the MB, seek an ISP who made it into the 20th century. I didn't think anyone still did that...

You could turn off NDRs to the Internet.

I was probably exaggerating as to the $1000 per megabit.

But we are on a 3000MB per month plan and when we go over this due to the bouncing email up to 8000MB last month it costs us over $1000 extra for the month.

Sorry for the stupidity but where can I configure to stop the resending. Would I set this to O in the delivery options in Virtual Server.

The help is much appreciated.

If you click 'Help' in the Default SMTP Virtual Server Properties screen, you will see the 'Expiration timeout'.
Set it to 0 Minutes, so it will deliver an NDR immediately and never resend.
