MailScanner and Perl problems (FIXED)

[Mike Jakubik]

Just wanted to mention to all the frustrated mailscanner users that have
been having issues when updating perl, the problem has finally been fixed.
I have submitted a pr to update the port, you will see this fix in version
4.79.4.

The problem was caused by the way mailscanner code behaved when it was ran
under perl's taint mode. Taint mode is triggered when changing the Run As
options in mailscanner's config.

If anyone is interested in updating their port now a diff can be found
here http://www.freebsd.org/cgi/query-pr.cgi?pr=141726 .

Many thanks to Julian for fixing this.
