Cant Receive emails with Exchange 2010
Posted on 2009-12-24
I have Exchange 2010 running on Windows 2008 R2 Ent server and cannot receive emails externally, however, I can send emails externally and internally.
The following is the configuration on the Server configuration Hub transport.
Hub transport connects directly to the Internet, so no external SMTP gateway is used.
2 send connectors enabled, client and custome Internet with anti-spam enabled.
Internet Send Connector:
Specify the FQDN this connector will provide = serv01.domain.corp
Network Local = All IPv4 with port 25
Network receive mail from remote servers = ISP smarthost IP address
Authentication = TLS only, enable Domain security unchecked
Permission groups = All checked except partners
Internal DNS lookups uses the network card and External DNS lookups uses 2 external DNS IP addresses.
MX and A records are alread setup with my ISP and is working as previously i had Windows 2003 R2 and Echange 2003 running.
When I telnet from outside the network and inside the network and directly on the box, I get
421 4.3.2 service not available
When i do a netstat -a, TCP port 25 is in a listening state, so i have no idea. I also had MS Forefront security for Exchange installed , but removed it.
Any help would be appreciated as I dont know where else to check.
