Blocked emails to customers

Hi,

Would this affect emails getting through to Virgin Media accounts (including blueyonder and ntlworld)? I work for a large retailer and have noticed a significant increase in the number of blocked emails since around 21st May. The error message we are seeing is "452 4.1.1 <xxxxxxx@ntlworld.com> requested action aborted: try again later;"  
Any insight into what is causing this would be appreciated, as it is causing great inconvenience to our customers as they are not receiving important service emails regarding their order.

Thanks

Re: Pop3 Authentication Errors

Hi Peglet25,

 

Thanks for your post and welcome to the Community Forums, This POP3 authentications issue should not be generating that delivery error. Have you checked to see if your domain is listed among any of the mail deliver services for delivery issues?

 

Cheers,

Corey C

Re: Pop3 Authentication Errors

No, I haven't checked that. Do you happen to have a link?

If I'm on the list, what do I do to fix it?

Re: Pop3 Authentication Errors

Thanks so much for replying, Peglet25,

 

That would be part of your organisation's web/network admin team, but you can also check your domain here: http://www.spamhaus.org/lookup/

 

Cheers,

Corey C

Re: Pop3 Authentication Errors

I've checked and our domain is fine. It is only Virgin Media domains that seem to be blocking our emails. Is there some way I can get my domain on your "trusted sender" list?

Re: Pop3 Authentication Errors

As a rule I'd always recommend checking the IP address of your outbound mail server rather than the domain.  Bear in mind also that while Spamhaus is one of the most well known of the Blacklist providers, they're not the only provider there is.

Try here:

https://mxtoolbox.com/blacklists.aspx

or here:

http://www.anti-abuse.org/multi-rbl-check/

These are two multi blacklist checkers.
