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.
