Postfix: No host option provided

I’m trying to test postfix locally by sending email via local telnet to RT.
At the moment I have no relay host configured since I’m attempting to use
local user accounts as the source address.

I’m getting the following from /var/log/mailllog:
…status=deferred (temporary failure. Command output: HTTP request failed:
500 No Host option provided. Your webserver logs may have more information
or there may be a network problem. )

Anyone have any experience with this particular issue?

what your RT aliases looks like?
what your http vhost configuration looks like?
