I have pve1.mydomain.ca added to (8) mail settings >> (4) transports but still get the below error I'm not sure what is the problem here? I'm probably missing something obvious.

Is pve1.mydomain.ca defined in your local DNS server?

What do you get when you execute the following?

doh had no A record in my dns for that been messing with an internal/external view setup and must have messed up that A record somewhere thanks for the help SOLVED

This can also occur if your DNS does not return MX records for the domain. This might happen if you're running split DNS, and the EFA ends up looking at the internal DNS servers instead of external.
