How does mail get sent to the members of an Exchange Distribution Group? Is the original message regenerated for however many are on the list or is it sent one time via BCC?

Exchange is a database, if the same email goes out to multiple users, it creates a pointer and sends that out to the users, the users then click on the pointer and open the email in the database

I am not sure if you are aware that the recipients are external (smtp addresses) None are local. Thanks

When you send a message to a DList, the expansion server looks at the list and then processes the recipients. Once the list is processed, the mail message is committed to the database and exchange creates a pointer which sits in the private information store. This in turn sends a notification to all the recipients that they have a message waiting. 1 message is generated and stored in the database for all the recipients in the list.

I just read your second comment. If you are sending the message internal, then the explination that I wrote applies. But if it is sent via the internet, a copy is sent to each address individually by the IMS.

Okay, is there a limit to how many recipients? In this case we are using an Exchange 2000 Server and the Distribution group contains roughly 350 members. Thanks.

Where would that be imposed? When we tried to send out our newsletter none of the SMTP addresses got the message. I am unsure of why it was unsuccessful. This list was imported via the utility csdev (sp?) and all the addresses are good. Thanks.

Its not nice to reject a correct answer. I'll keep my eye on you...very ungrateful...

by neo330

If you sent a message and the message was rejected, what was the error message that was stated in the NDR that you received?

How else will I get more answers if I accept before I am ready? I am very grateful and plan on accepting the answer.
