Hi,
We have a customer who is trying to connect to a company with hosted Messagelabs email security via Forcepoint servers using TLS.
We can connect to the primary MX record fine but the secondary MX record gives the following:-
Trying Server cluster2a.eu.messagelabs.com
SMTP test:
A connection attempt from rly25a.srv.mailcontrol.com:8882 to cluster2a.eu.messagelabs.com on the SMTP port returns:
220 server-12.tower-555.messagelabs.com ESMTP
------------------------------------------------------------
Traceroute reports that the path to cluster2a.eu.messagelabs.com from this cluster is:
