My company uses a custom automated program to send promotional emails to our customers. For some of them they go out with regular email addresses in the "from" field, and for others they go out with distribution list email addresses, so when the undeliverables return, a few staffers can share the responsibility of weeding them out.
For some reason, the undeliverables do not go to the distribution list members, though, for the ones with the regular email addresses in the from field, they get them just fine.
We use Symantec.Cloud for our spam filtering, and they did a track and trace to confirm that the undeliverables did go through they're system and get forwarded to our exchange server, but does Exchange have a policy of deleting undeliverables for distribution list email addresses?
I am on Exchange 2003. Thanks so much!
