In Ironmail Advanced Server 6.7.2 mails are not going to particular domain. As this our parent group domain, there are number of mails pending in the outbound queue.
Mails to rest of the outside domain are going fine.
Please let me know a way to resolve this issue. As McAfee is no more supporting Ironmail 6.7.2, I need anyone to help me out from this mess.
I feel your pain. I have some issues also and not getting any answers.
