Documentation

Whether sendmail should issue a warning header if called with "-f".

The sendmail program has a useful feature to let you set the envelope FROM address via a command line option, "-f". 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.

This variable was added, or its default value changed, in Emacs 24.1.
