Never mind - I should have searched first

Sorry for the spam guys.
I found the answer to my questions:
Mutt also supports a ``batch'' mode to send prepared messages. Simply 
redirect input from the file you wish to send. For example,

mutt -s "data set for run #2" profes...@bigschool.edu < ~/run2.dat

This command will send a message to ``profes...@bigschool.edu'' with a 
subject of ``data set for run #2''. In the body of the message will be the 
contents of the file ``~/run2.dat''.
