I'm having some difficulty applying this.  It's going into a perl file
thusly:

$logmsg =~ s|/((Mon|Tues?|Wed|Thu(rs?)?|Fri|Sat|Sun)\s+(Jan|Feb|Mar|Apr|
May|June?|July?|Aug|Sep|Oct|Nov|Dec)\s+[0-3]?[0-9]\s+(19|20)[0-9][0-9]\s
+[^<]+<[^\s ]+@[^\s@>]+>\s+2.[4-6].[0-9.-]+\s*)/|mg

But that gives me Unmatched ( in regex; marked by <-- HERE in m/(( <--
HERE  or something along those lines.

The added "s|...|mg" is coming from other lines in this script which
look like:

$logmsg =~ s|^\s*\d\d*-\d\d*-\d\d*\s*[^<\n]*<[^>\n]*>\s*$|* \n|mg;

so I'm sure I'm screwing something up when putting it in the script.
