Yep. mutt is invoking sendmail directly to queue the outgoing message.

You do need sendmail configured (sendmail.cf set up appropriately), and you do need to run the queue when you're ready to transmit the outgoing messages, but you don't need the daemon. When the Wifi link comes up, instead of restarting a daemon, all that's needed is to run "sendmail -q" or "sendmail -qf". The advantage of the -qf form is that -- if I'm reading the manpage correctly -- it won't return until everything has been sent (at which point you can shut down the link, unless it's being used for something else -- like incoming messages). A sendmail daemon is useful in an always-connected system, to receive messages that someone pushes to it via SMTP or to retry queued transmissions periodically if the receiving system (or the path to it) was down on the first attempt. As the first responder was saying, it's really not all that useful on a system that is connected to the Internet only occasionally.
