This is a file of mail address aliases used when sending mail. The name of the file can be anything you want. You will probably want to set the "source" and "set alias_file" statements in muttrc to match the name you use.

alias adsm-l                  adsm-l@vm.marist.edu
alias ghi          "abc.def@earthlink.net (GHI Office)"

Alias file maintenance can be done by using any text editor on the alias file, or by using mutt's alias and unalias commands. There is an abook package for address book maintenance. SLUUG has not evaluated or installed it.
