cluster5.eu.messagelabs.com at 85.158.138.179 is refusing to talk to one of my SMTP servers at 23.239.151.125. When my server connects, cluster5 immediately responds with:
501 Connection rejected by policy [7.7] 18806, please visit www.messagelabs.com/support for more details about this error message.
This is instead of the initial greeting, before even HELO/EHLO has been issued.
No spam is being sent through 23.239.151.125 and it is clean according to all RBLs that I'm aware of.
Please investigate / unblock.
Thank you,
Lennart Lövstrand
BTW, the URL in the response just redirects to https://www.symantec.com/products/endpoint-hybrid-... and is unfortuantely of no help. I think many of us would appreciate it if you could update it to something more meaningful. Thanks.
