I find it useful to configure the local MTA on my laptop anyway; my mutt 
just delivers locally. That way I can compose and dispatch email when 
offline (eg on a train) and it just queues and goes when back online.  
Also, everything else on the machine which uses email (such as cron) can 
deliver email too, for free!

Case in point: my Mac here comes with postfix preinstalled from the 
vendor, one just suitably modifies /etc/postfix/main.cf. I deliver to 
the local ISP's SMTP service. (Actually, since the laptop moves, this 
involves a local haproxy and a Byzantine system of ssh tunnels etc, but 
that's by the by.)

So the local sendmail command is my proxy, and mutt doesn't know 
anything special.

Ian's suggestion, though, sounds like what you want.
