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
