Our SMTP server IP is blocked, unable send emails to Virginmedia recipients

Hello,
 
Our SMTP server IP address appears to be blocked/blacklisted by Virginmedia.
 
Due to this, we are unable to send emails to the recipients at
 

virginmedia.com, ntlworld.com, blueyonder.co.uk

 

Our emails are being deferred and the error messages are:

 

host mx.tb.ukmail.iss.... refused to talk to me: 421 mx5.tb.ukmail.iss.... mx5.tb.ukmail.iss.... MXIN107 Connections from your IP <our_IP> have been disallowed by admin policy.

 
We have blacklist monitoring enabled and we know this IP address is not on any blacklists.
 
Could somebody from Virginmedia.com please help us unblock our IP address ?
 
Thank you in advance!

Re: Our SMTP server IP is blocked, unable send emails to Virginmedia recipients

guess your server has been sending spam. check that out first or you will just keep getting banned

Re: Our SMTP server IP is blocked, unable send emails to Virginmedia recipients

We are not sending spam and our emails are signed with SPF and DKIM. We have feedback loops set up with all major providers.

We also monitor blacklists and we know this IP address is not on any blacklist.

Is there a more direct way to get in touch with Virginmedia team that deals with these issues or escalate this ticket somehow?

TIA!

Could somebody from the Virgin Media team please look into our issue and help us resolve this?

We have not been able to deliver legitimate emails to Virgin Media recipients for a few weeks now and have not received any responses from the team.

Is there another way to reach them?
