A Better way is to have your local MTA collect messages (assuming you want
to do your mail writing offline ..) and relay them through another SMTP
server.
With your scenario, what happens if the host you're trying to send a
message to is unreachable ?
SMTP retries are handled better witha host connected to the net 24H ..

Ofcourse. So in your case you rewrite the headers to say
"From: $user@$isp" ..

ITYM for relaying. That's a poorly configured mail server. they should
allow relay by IP, either from connection, or from comparing the `HELO'
one ..
If they can't match IPs, there's always the pop-before-smtp way ..
