Thanks for the suggestion but that doesn't work....I did try it as follows:
Domain1.tld created on ISP config as a site, set to external mailserver
Domain2.tld added as a co-domain, set to local mailserver.
When emailing
anything@Domain2.tld, I receive a bounce message saying user does not exist in local user table.
So then I create a catchall on User/Email tab on Domain1.tld
When emailing
anything@Domain2.tld, the email is accepted and delivered into the catchall POP mailbox, but the email is not automatically forwarded to
anything@Domain1.tld (external mailserver) which is what I want to happen.
Any further advice or suggestions?
Steve.
