 I don't know if it helps, but last time someone suggested that Postfix
didn't recognize myhostname as linux.local, which didn't make sense to
me because it sends and receives fine as racswfrontiernet.net. But
anyhow, not knowing what to try, I changed myorigin to frontiernet.net
instead of mydomain, and resent the message.
  This time I did not get an "MX" error, rather the one below:

Final Recipient: rfc; racswfrontiernet.net
Action: failed
Status: 5.0.0
Diagnostic -Code; X-Postfix; unknown user "racsw"

Regardless, I changed it back so I can get normal mail (as racsw...),
and am here as a result to try and fix this.

Robert
