Issue #1 - Message sent to those in the Sys​::Syslog file bounces.

  It would seem that all four e-mail addresses listed in Sys​::Syslog   no longer works\, in particular tchrist@​convex.com\,   lwall@​jpl-devvax.jpl.nasa.gov\, robinson_s@​sc.maricopa.edu\,   Tim.Bunce@​ig.co.uk. Perhaps they could be updated\, or at least   a note to that effect put into place?

Issue #2 - Defaults in Sys​::Syslog are non-intuitive. Below is a   message I originally attempted to send to the four   addresses above.

  The four of you have your names on Sys​::Syslog\, which is why I'm   contacting you. I recently ran into some confusion\, admittedly of   my own making\, but it seems like the defaults of Sys​::Syslog leave   something to be desired.  
  FreeBSD (my test platform) and many other operating systems today   allow for "secure" syslog\, which really means don't accept inet   domain messages. This is done to prevent syslog from becoming a   remote disk filling service. This has no effect on C programs   because the libc variant of the syslog functions only uses unix   domain sockets for communication. In FreeBSD see   /usr/src/lib/libc/gen/syslog.c\, in particular connectlog().  
  For some reason\, possibly a good one\, Sys​::Syslog defaults to inet\,   rather than unix. The net result on these "secure" syslog setups   is that Sys​::Syslog becomes non-functional out of the box. This   is of course fixable\, as documented in the Sys​::Syslog man page\,   with setlogsock('unix') -- however that is counter-intuitive.   Indeed\, the very top of the man page proclaims​:  
  NAME   Sys​::Syslog\, openlog\, closelog\, setlogmask\, syslog - Perl   interface to the UNIX syslog(3) calls  
  One would expect the interface to syslog(3) to have the same defaults   as syslog(3).  
  Is there a reason that the perl library was defaulted to inet? Is   there any support for changing the default to unix?

Background bug information​:

  Although I'm using perlbug to submit this\, which is including   information from my local machine this problem seems to be in all   versions of perl 5.x.

This does not seem to be a problem in 5.8.0's Sys​::Syslog. According to the documentation\, by default the types tcp\, udp\, unix\, stream\, console are tried in order. It also seems to work on my FreeBSD 4.7 system (syslogd is started with -s flag) without specifying setlogsock().

Agreed. 5.8 seems to have fixed the problem. Good enough for me.
