There is a small problem in the above distribution in the CPAN archive.

The following is an extract from a CPAN session

cpan> make Mail​::Mailer
Running make for GBARR/MailTools-1.14.tar.gz
  Unwrapped into directory d​:/CPAN/build/MailTools-1.14

  CPAN.pm​: Going to build GBARR/MailTools-1.14.tar.gz

Checking for Net​::SMTP...ok
Checking for Net​::Domain...ok
Checking for IO​::Handle...ok
Checking if your kit is complete...
Looks good

Although this is on OS/2, the problem looks to be in the POD entries in
Mail/Cap.pm

The problem is easy to fix (just a missing '>') but has found its' way
onto CPAN - or, at least the mirror that I use!
