I have a user that is not getting some e-mails from the outside. The people sending him e-mails receive a NDR with this error.

because:  Error transferring to emailserver.MYDOMAIN.COM; SMTP Protocol Returned a Permanent Error 554 mail server permanently rejected message (#5.3.0)

I looked it into and according to microsoft ( the issue lies in my firewall configuration which we just migrated about 2 months ago. I submitted a ticket with Cisco and I am waiting to hear back.

However, has anyone seen this error and knows what else might contribute and what else I can do to rectify this.
