As mentioned by Noel, relay_domains must not have []. The [] are
not supported here by Postfix documentation.
> relayhost = ns4.arlut.utexas.edu
As mentioned by Noel, this needs [] to avoid MX lookups (the MX
hosts for ns4.arlut.utexas.edu are mxhost2.arlut.utexas.edu
and mxhost1.arlut.utexas.edu.). The [] are recommended by
Postfix documentation when you want to relay to a hostname.
