I need a solution
We are experiancing timeout when we are sending emails to some of our clients.
Host cluster5.us.messagelabs.com reply is connection time out. Meanwhile we can connect to other services via 25 port , but only message labs give us this error.
Source IP address: 65.52.22.183
Trying to telnet to the device directly from our device to port 25 but we still got an error. Any ideas ?
