Unfortunately, it also has a widely
 disliked default behavior of selling you out if you do that by inserting
 an unattractive warning in the headers.  It looks something like this:
 
-  X-Authentication-Warning: u1.example.com: niceguy set sender to 
niceguy@example.com using -f
-
-It is possible to configure sendmail to not do this, but such a reconfiguration
-is not an option for many users.  As this is the default behavior of most
-sendmail installations, one can mostly only wish it were otherwise.  If 
feedmail
-believes the sendmail program will sell you out this way, it won't use the 
\"-f\"
-option when calling sendmail.  If it doesn't think sendmail will sell you out,
-it will use the \"-f\" \(since it is a handy feature).  You control what
-feedmail thinks with this variable.  The default is nil, meaning that feedmail
-will believe that sendmail will sell you out."
