I added the user under domain ->> blah.com → users and yet I still get this return email when I try to send test emails to the account:
Google tried to deliver your message, but it was rejected by the server for the recipient domain blah.com by mxsrv1.spamgateway.comodo.com. [126.96.36.199].
The error that the other server returned was:
550 no mailbox by that name is currently available
Is the add users section of the new version of this site broken? It doesn’t match up with the help documentation.
Nope - not a dead forum.
Issues like this are usually sent on to our support desk firstname.lastname@example.org, which gets swifter attention.
Does the user exist on the destination mail-server?
