Hi All,
I have a new install of Exchange 2010, not a migration.
I have a cas/hubt server, mailbox server and edge server
I can send/receive internal emails. I can send emails externally. I cannot receive emails from external sources.
I've gone alot of searching on this and nothing has helped so far. Both my client and Default receive connectors have Anonymous users checked under Permission Groups. I have turned off firewalls and UAC on all servers. I'm using an ASA firewall on the outside but I checked with Cisco and it is properly forwarding port 25 to my edge.
I have reinstalled the CAS/HubT server and i'm still not any further.
I can telnet port 25 to my edge server correctly. I can telnet port 25 to my cas/hubt server.
I'm stumped!!!!! HELP!
