Hi,
We have just provissioned two new servers and we have received complainst from numerous customers that were migrated to the servers that emails they are sending to clients that use MessageLabs are not arriving.One of my clients cannot send email to his bank or his solicitiors both of them mananged by MessageLabs.
The server IP's
221.121.138.55
221.121.138.85
I can see from the logs that the messages are successful in being delivered yet they arent getting to the client:
2017-05-17 16:56:19 1dAssW-0046v8-M4 => user@domain <user@domain> R=dkim_lookuphost T=dkim_remote_smtp H=cluster4.us.messagelabs.com [216.82.251.33] X=TLSv1.2:DHE-RSA-AES256-GCM-SHA384:256 CV=yes C="250 ok 1495004179 qp 141302 server-13.tower-130.messagelabs.com!1495004176!110755568!1"
2017-05-17 16:56:19 1dAssW-0046v8-M4 Completed
This only happens with MessageLab managed companies and have no problem with others.
Thank you.
