5     # reads e-mail addresses from stdin and dump format for .htusers on stdout
6     # which will use auth_pop3 for user authentification

8     # This tool is good for batch import and it will do it's best to resolve
9     # all sendmail related output from expn. However, it's not tested on
10     # other mailers.
