We have been having a problem emailing to a customer whose server is =
hosted by The Planet (http://www.theplanet.com/). Our mail server is =
hosted in-house on a comcast business connection.
IP address of our server is: 173.13.45.23
Customers mail server is: 69.93.203.243
I cannot telnet to port 25 on their server, and they cannot telnet to =
port 25 on ours.
If I try to connect to their mail server from a different network such =
as my home internet connection, I can connect.
We do not do any firewalling that would block this in anyway. We were =
able to send and receive email to them when we used Qwest for our =
connection, before we switched to Comcast.
Comcast has said the problem is not on their end because it times out at =
The Planet.
The Planet doesn't have much interest in speaking with me, because I'm =
not their customer.
Not sure what to do at this point.
