I have a problem in where a pop3/imap4 client sends an email to a Distribution List in Active Directory. Mail Marshall recieves the email, processed it and forwards it to Exchange but the email is not recieved in DL Members' inbox.
We're rolling out RPC which will resolve this problem, however the the rollout phase will be over the next few months and pop3/imap4 clients will still be live.
Exchange 2003 Front-End
- OWA and soon to be RPC Proxy
Exchange 2003 Back-End
- POP3 and IMAP4 services are and running, I know this should be done through the front-end but this required
setting up another 'domain' for Exchange which my organisation was not keen on.
- SMTP VSI set to allow relaying from Mail Marshal and Domain Users, Authenticated Users has default options set.
Mail Marshall SMTP
- Processes all SMTP deliveries
I've visited Simon's website and found this article http://www.amset.info/exchange/smtp-relaysecure.asp
. Just wondering if anyone else has come across this problem and what was their resolution.
