UIUC Mathematics Email Migration - Plain Mail

Plain old Linux mail will work, but with a caveat.

Q. Sometimes I like to send off a quick message using the 'mail'
command on a Linux terminal.  Will I still be able to do so.

A. Yes, but with a caveat.  The caveat is that particular message will
not be integrated with the campus email server.  So you will have no
record of it being sent.
