I need a solution
Hi,
We are experincing difficulties sending mails to some systems that are using Message Labs
Connecting to Mediaset we receive this error:
501 Connection rejected by policy [7.7] 2705, please visit www.messagelabs.com/support for more details about this error message.
We tried also to delist our IPs with this tool:
But it say that our IPs haven't negative reputation so they cannot be delisted.
Below you can find our IP list:
54.36.55.250
54.36.76.127
54.36.103.105
54.36.11.6
we aren't in any blacklist, and we are not sending spam.
Please can you check why we are blocked?
Thanks.
