E-mail DNS issue for Virgin Media Domains

Hello,

We are getting this error when we try and connect to Virgin Media e-mail servers for our Virgin Media customers:

Your HELO/EHLO mail.iggsoftware.com is not matching your DNS configuration...

(This error only happens with Virgin Media customer domains i.e. @blueyonder.co.uk... we are sending out a no-reply e-mail, no-reply@iggsoftware.com)

We looked at our spf record and did not see anything wrong, can one of Virgin Media's tech folk do a spf lookup against our domain and see why we might be denied?

Thanks for the guidance!

Re: E-mail DNS issue for Virgin Media Domains

This is nothing to do with SPF and more to do with your reverse DNS AFAICT

However inspecting the mail.iggsoftware.com  The forward and reverse DNS appear to match.  I have my own email server, if I drop you my email address via PM, would you be willing to send me a mail so I can have a look at how your server talks to mine?

Re: E-mail DNS issue for Virgin Media Domains

As expected this is nothing to do with SPF

The email server isn't using best sending practices.

@HappyPath - Take a read of this.  It'll help you understand the PM I sent you:

I'd like to share the received line in full on here so I can explain to anyone else who might come across the thread.  May I do so?
