 Special.
 See below.
 .Sh DESCRIPTION
-At one time, the only Mail Transfer Agent (MTA) software easily available
-was
-.Xr sendmail 8 .
-As a result of this, most Mail User Agents (MUAs) such as
-.Xr mail 1
-had the path and calling conventions expected by

-It would be difficult to modify all MUA software typically available

-in

 The program knows to behave differently when its

 Configuration for

 or does not contain a mapping for the name under which it was invoked.

 The entire reason this program exists is a crock.
 Instead, a command
