Hi!

Our domain is nv.ua, our smtp-server is mx1.nv.ua (91.90.196.19)

When we try to send email to someone at @chanel-corp.com we receive this message:

"501 Connection rejected by policy [7.7] 4310, please visit www.messagelabs.com/support for more details about this error message.

Connection to host lost."

Please help us to delist our Public IP 91.90.196.19 from your SPAM filter.

Thanks!
