Updated p5-MailTools to 1.58

Changes :
- add utf8 support [Philip Molter]
- copyright notices fixed, date updated
- And again, the patches of Autrijus had to be adapted to run on
  a perl 5.6.1 installation.  Thanks to [Philip Molter]
- Mail::Util::maildomain() if no information about domains
  is found in sendmail.cf, no error should be reported.
  [Vaughn Skinner]
- Removed the possibility to use 'mailx', which was the
  default: removal from the detectionn routines and Mail/Mailer/mail.pm.
  Strongly suggested by [Sebastian Krahmer]
- Mail::Util::domainname() Patch to remove use of S variable from
  sendmail.cf, because its inclusion is contra-productive.
  [Timur Bakeyev]
- Mail::Util::domainname() Clean domain from sendmail.cf from
  trailing trash (if present) [Timur Bakeyev]
- Mail::Util::domainname()  Added environment variable MAILDOMAIN
  to overrule smart domain discovery. [Timur Bakeyev]
- Fixed some typos
- perl5.8.0 utf8 and unicode bugs fixed
