in front of our domino-system a ironport-cluster (2*C350) is running. Last wee we set up a virtual gateway for senden our newsletter.
Normal Mails are send with @companyname.com and the newsletter-mail with @newsletter.companyname.com
Everythin works fine BUT when sending mails from @newsletter.companyname.com to @companyname no mails are recieved. The Ironport-Tracking just says "Mail queued for delivery" and the domino-system is retrieving nothing.
Where can i find out, whereto the mails are send?
Any ideas where the failure could be?
