        - do not try passing an empty string as a Failure message

1.300013  2014-08-28 11:00:16-04:00 America/New_York
        - sometimes, if no error is given and $smtp->message returns (),
          the arguments to the Failure constructor were out of alignment and
          the failure's error message would be "code"; this has been fixed

        - documentation fix: there's no Email::MIME->delete_header
          (thanks, Kris Matthews)

1.300011  2014-03-02 18:16:12-05:00 America/New_York
        - run the sendmail program with -i by default (thanks, William Blunn)
        - do not die when a race causes mkpath(Maildir/new) to fail because the
          directory already exists

1.300010  2014-01-11 14:15:13-05:00 America/New_York
        - the SMTP transport now has a "debug" option

          at long last, Sendmail and Maildir transports replaces CRLF with CR
          before piping

          [BUG FIXES]
          fixes a bug where recipients beginning with a - would not work with
          the Sendmail transport [rt.perl.org #66246]
