Update to 0.79:

0.79   same as 0.78_6

0.78_6 06.02.2003
       - Remove old configuration variables from version 0.74.
       - document $mail{Sender}
       - add seconds to Date header (some buggy mailers freak out if
         the time has no seconds)
       - added "/" (\x2F) as a valid character in mailbox part.
       - minor documentation updates

0.78_5 24.08.2002
       - Adapt reference to mail headers in module to new case convention
         (bug introduced in 0.78_2).
       - ppd and PPM install changes...

0.78_4
         no change in module, only in PPM distribution

0.78_3 11.08.2002
       - support multi-line responses
       - define local $\ and $_ in &sendmail to protect us from outside
         settings (is this really needed?)
       - delete $mail{Sender} used for envelope sender, but not needed as
         header
       - internal rewrite using subs to send and receive on socket

0.78_2 11.08.2002
       - fix old bug with dot as 76th char disappearing.
       - correct very old bug where port number was not extracted from
         stuff like 'my.server:2525'.
       - fix time_to_date bug with negative half-hour zones (only Newfoundland?)
       - use Sys::Hostname to get the hostname for HELO. (I think it has
         been part of the standard distribution for many years now)
       - support different envelope sender through $mail{Sender}
       - Change case of headers: first character after "-" also uppercased
         now, so people who believe this is required because Outlook does it
         this way stop complaining. :-)
       - Enable full session output for debugging
       - Do not copy the mail message again to a different variable.
       - Minor documentation changes.
