First, i realize this isn't an ASSP forum but I know I'm not the only one using ASSP so thought I would wask.
So, sending a test from email@example.com to firstname.lastname@example.org (domain i host) which in turn forwards to email@example.com bounces back with relaying not allowed because it isn't a local domain.
The exact error is
<firstname.lastname@example.org>: host assp.local.com[10.100.100.61] said: 530
Relaying not allowed - sender domain not local (in reply to end of DATA
How do I allow relaying here? If I send from a local test account on a domain that I host it works fine but from external no go.
