Title: default to sendmail command again to allow for lightweight MTAs

probably the reason why people had problems with the sendmail-command
method was because the code passed an invalid envelope-from string. Fix
that by removing the envelope from and have it set by the MTA.

Also switch from the deprecated popen2 to using corresponding methods of
the subprocess module.
