2013 SP1 -separate servers for MBX and CAS - 4 of each. Exchange 2007 configured as a CCR
I am in co-existence mode but have not yet switched on the legacy.domainname.com. I have a new certificate installed on all servers - 2007 and 2013 with the legacy namespace included
I can receive on the exchange 2013 servers and can send to exchange 2013 users but cannot send to 2007 users or externally. I have enabled protocol logging and I'm seeing:
2014-04-02T00:57:31.476Z,Outbound Primary,08D1120CF8FEEDBA,0,,10.0.9.1:25,*,,attempting to connect
2014-04-02T00:57:52.521Z,Outbound Primary,08D1120CF8FEEDBA,1,,10.0.9.1:25,*,,"Failed to connect. Winsock error code: 10060, Win32 error code: 10060, Error Message: A connection attempt failed because the connected party did not properly respond after a
period of time, or established connection failed because connected host has failed to respond 10.0.9.1:25"
The client has a pair of Axway mailgateway appliances (Tumbleweed). We can Telnet between the exchange 2013 servers and the Axways. There is a firewall between these mail gateways and the exchange servers and the following ports were opened - 25,443,465,995,110
I used the existing send connectors from 2007 and just added the mailbox servers to them. I created 2 new receive connectors to match 2 specialist 2007 connectors.
But I still can't send mail. Any suggestions where next to check?
