Add approved external domain to bypass SMTP relay restriction

Hi all,

I have a domain ( residing on shared hosting space. This domain provides its own SMTP service, but of late, it sucks and keeps falling over.

I also have a cPanel/WHM VPS ( that works just great.

I want [email protected] to be able to send emails through (authenticated by a custom user email account I set up in's cPanel just for this purpose - [email protected]) over SMTP.

No encryption necessary. I don't however want to disable the relay entirely, I just want antirelayd to regard any originating address of as "approved".

What is the best way of doing this?

Thanks! :)
