Log Message:
Release 2.68 is mostly a bug-fix release; the most important changes are:

* Detect Sys::Syslog vs. Unix::Syslog at run-time
  rather than when running ./configure.
* Bug fix: Don't change Content-Disposition to "inline" by default.
  This was causing weird bugs with Outlook iCalendar attachments.
* Various crash fixes.
* Make relay_is_blacklisted and relay_is_blacklisted_multi handle
  IPv6 addresses.
* Make the C code call smfi_setmlreply if the milter library supports it
  and the Perl code returns a multi-line reply.

(And take over maintainer)
