Emails bouncing back from Virgin Media

[mdrabble]

Having a bit of a strange issue with NTLWorld and VirignMedia emails where our emails are bouncing back from this with the error Remote Server returned '554 5.2.0 NbJB1r00f0GHFFd01bJBij Spam content found'

 

I've check various things and all is fine our end.

 

I've tried to contact Virgin Media who were very unhelpful as we are not virgin media customers.

 

Anyone else had issues recently with VirginMedia and email bounce backs? Or any other suggestions I try.

 

 

Cheers

It may be worth checking to see if your IP has been blacklisted. Different companies use different blacklist services and it may be that Virgin / NTL use one on which your IP address is listed. Blacklist Check would be a good starting point.

 

It's normally pretty simple to get yourself removed, providing you don't have open relays or similar.

Not listed on blacklists - looking at different pages on the Virgin media forums - could be down to not having a PTR record.

 

Ive asked my ISP to add a PTR record for my mx record and will check again using mxtoolbox.com and will also check by sending another email.

Still no joy - after more reading it could be down to recent changes at virgin media.

 

I'm wondering if anyone else is having similar issues with virginmedia/ntlworld/bloueyonder etc.

I'm with vm at home but not had any problems receiving from work.

@virginmedia email address are fine it @ntlworld that are causing the issues unless they disable the spam filters.

 

After finally talking to VM they sent this reply. To which I've asked to be white listed, so fingers crossed.

 

Thanks for coming back to us, it sounds like your exchange may be affected by the new mail platforms SPF policy, you can find more information about this in the statement here.

 

If your able to implement a 'Sender Re-writing Scheme' on your exchange this should resolve the sending problems, alternatively we can look to white list your domains IP address our end to allow access.

 

Their new policy statement:

 

Virgin Media implement SPF authentication on all inbound email, honouring all SPF policies including those that specify ‘hard fail when authentication fails.

 

An SPF policy is specified by the sender’s email domain and advises receiving mail platforms which IP addresses or hosts are authorised to send email for that domain. If an email is sent from an IP Address or host that is not authorised by the sender’s domain, it will fail SPF authentication. If the SPF policy of the sender’s email domain specifies ‘hard fail’ Virgin Media will not deliver that email.

 

Applying SPF Authentication helps prevent Spam, Phishing and Spoofed emails and is in the best interests of the vast majority of our customers.

 

However, if you utilise an email forwarding service to deliver mail to the Virgin Media email platform, you may experience problems receiving mail if the forwarding domain is not SPF-aware. A forwarding service may be used to host a bespoke email domain and have emails sent from this to a Virgin Media Mail account.

 

If you are experiencing issues of this nature, we recommend that you use a forwarding provider that implements the Sender Rewriting Scheme (SRS) such as 1and1.com or alternatively request your existing provider adopt this approach to email forwarding.

 

Alternatively we are able to remove SPF authentication from customer accounts. However this approach will remove valuable protection against email spoofing from your email account. As such any customer requesting the removal of this feature must be aware that extra vigilance will be needed going forward.

 

If you are experiencing an issue with email forwarding or would like to request your email to be opted-out, please create a new thread, and we will be able to help.
