rDNS doesn't match HELO

Hello

Our ISP has changed due to a buy out and our new ISP (SKY Broadband) will not change the rDNS record for our domain.

OUr rDNS used to be "mail.ourdomain.com" and mail went out fine, it's now "xxxxxx.skybroadband.com" and we are having some mail bounce and get refused.

What are my options, can I set my HELO to xxxxxx.skybroadband.com and if I do will I need to make any other DNS changes or will it have a negative effect.

My other option is to move ISP which i'll do as a last resort

Thanks for your time

Dave

Are they giving you a Fixed IP Address?  I somehow doubt it as we were in the same boat and ended switching ISP's to one that supports businesses and Fixed IP's and thus Reverse DNS.

Hi Alan,

Yes we have a static IP as we migrated from BeThere Broadband but Sky will not entertain the idea of changing rDNS

So were we!

What is their issue with Reverse DNS?  If they provide you with the IP Address, they need to set the Reverse DNS to what you need and if they can't / won't, then leave them for an ISP that can and will.

Hi Alan,

That's pretty definitive and is what I'm leaning towards, just have to convince MD now

Thanks

We didn't migrate to them from BeThere because they couldn't offer us multiple fixed IP's, so that's another good reason to move away from them (if you need any more).

Instead it helped encourage us to move office and ISP's at the same time to one that could (sadly BT for Infinity), but at least we got everything that we wanted including speed.  I won't go into the debacle that occurred as a result of ordering two new lines with Infinity on them with BT, but suffice it to say it didn't go smoothly!

Good luck with the MD.
