Email Security.cloud

Hello,

Our emails sent by our clients at midsouthtransport.com are getting delivery error "501 Connection rejected by policy [7.7]. I have checked and our server IP address 162.144.39.143 and it is not blacklisted. The client does use SpamExperts.com and I can see that one of their IP addresses lastmx.spamexperts.net IP 209.58.136.65 IS blacklisted by BACKSCATTERER but since that is a program designed to protect from spam in incoming emails and not outgoing emails I don't know why it would affect our server reputation or cause a problem getting emails to Messagelabs.net clients.

The bounce back messages look like this:

Submit a sample of the email that's getting blocked to:

investigation@review.symantec.com

I have, twice now, and my client has once and I have not recieved a response. This has been going on for too long.

I need to know why messagelabs.net/Symantec is blocking emails from our server (IP 162.144.39.143). We do not show on the Symantec blacklist.

I have submitted the information requested twice now, my client submitted it once. I haven't recieved a responce. This has been going on for a month and a half now. Please help.

Hello Mia,

Hope you're doing well.

First, accept our apologies for the delay in addressing the issue. I want to inform you that issue with the IP and our systems has been corrected.

Thanks

Roberto
