=head1 NAME

Mail::Util - mail utility functions

=head1 INHERITANCE

 Mail::Util
   is a Exporter

=head1 SYNOPSIS

  use Mail::Util qw( ... );

=head1 DESCRIPTION

This package provides several mail related utility functions. Any function
required must by explicitly listed on the use line to be exported into
the calling package.

=head1 FUNCTIONS

=over 4

=item B<mailaddress>( [$address] )

Return a guess at the current users mail address. The user can force
the return value by setting the MAILADDRESS environment variable.
[2.10] You may set the $address via the parameter.

WARNING:
When not supplied via the environment variable, <mailaddress> looks at
various configuration files and other environmental data. Although this
seems to be smart behavior, this is not predictable enough (IMHO) to
be used.  Please set the MAILADDRESS explicitly, and do not trust on
the "automatic detection", even when that produces a correct address
(on the moment)

example: 

 # in your main script
 $ENV{MAILADDRESS} = '[email protected]';

 # everywhere else
 use Mail::Util 'mailaddress';
 print mailaddress;

 # since v2.10
 mailaddress "[email protected]";

=item B<maildomain>()

Attempt to determine the current user mail domain string via the following
methods

=over 4

=item * Look for the MAILDOMAIN environment variable, which can be set from outside the program.  This is by far the best way to configure the domain.

=item * Look for a sendmail.cf file and extract DH parameter

=item * Look for a smail config file and usr the first host defined in hostname(s)

=item * Try an SMTP connect (if Net::SMTP exists) first to mailhost then localhost

=item * Use value from Net::Domain::domainname (if Net::Domain exists)

=back

WARNING:
On modern machines, there is only one good way to provide information to
this method: the first; always explicitly configure the MAILDOMAIN.

example: 

 # in your main script
 $ENV{MAILDOMAIN} = 'example.com';

 # everywhere else
 use Mail::Util 'maildomain';
 print maildomain;

=item B<read_mbox>($file)

Read $file, a binmail mailbox file, and return a list of  references.
Each reference is a reference to an array containing one message.

WARNING:
This method does not quote lines which accidentally also start with the
message separator C<From>, so this implementation can be considered
broken.  See Mail::Box::Mbox
