I have a customer who made a mess of things setting up google apps. She has now closed her google apps account and we are getting emails via POP to gmail successfully using gmail fetch.
However in gmail when trying to add her domain email address [email protected] as a FROM, after adding the SMTP mail server mail.domain.com, the verify email bounces with the error
Technical details of temporary failure:
DNS Error: Address resolution of mail.domain.com.domain.com.
It looks to me like the domain might still be somewhere in google DNS and pre-pending the mailserver to it...
Or something like that. Any ideas anyone?
[UPDATE] I just realised, that even if I used a different mail server when adding the addition email address the error is the same. i.e. if I add as the SMTP server mail.mymailserver.com
then the bounce still says DNS Error: Address resolution of mail.domain.com.domain.com.
I have no idea where it is getting that from.
