I'm slowly deciphering the bounce message. Apparently, courier--mutt isn't doing this--is forcing my From: address to benfell@graton. graton is the not fully qualified domain name of the system. And my mail should be going out as benf...@parts-unknown.org.Why would this be happening?
If Mutt does not specify the envelope return address using the -f option to sendmail, Courier has to come up with one. Your system loginid becomes the username portion, and the domain comes from the $sysconfdir/defaultdomain or $sysconfdir/me, whichever comes first, or if neither file exists, your system hostname.
You probably have neither $sysconfdir/defaultdomain or $sysconfdir/me, and that's what your hostname comes out to be.
You can either define them, as described in the courier man page, or you can set some environment variables in your shell, see "RETURN ADDRESS" in Courier's sendmail man page.
Also, all of this presumes that mutt runs the sendmail command in order to send its email. I haven't used mutt in years, and I don't remember what it does for sending email. It might be connecting to localhost port 25, and talking SMTP. If this is what it does, mutt is entirely responsible for giving the return address in the SMTP FROM command, so you'll have to fix mutt's configuration. I'm fairly certain that mutt must have a setting somewhere that explicitly sets the return address it uses.
