Hi,
We recently moved to a new Dedicated Server and we are having issues delivering mail to your messagelabs.com servers.
Our IP is 72.9.154.92 and we have only been using it for the last month.
LOG: MAIN
H=cluster4.us.messagelabs.com [216.82.242.33] Connection timed out
Connecting to cluster4.us.messagelabs.com [216.82.251.33]:25 ... failed: Connection timed out (timeout=5m)
Thanks
