NAME

       Mail::Mailer - send simple emails

INHERITANCE

        Mail::Mailer
          is an IO::Handle

SYNOPSIS

         use Mail::Mailer;
         use Mail::Mailer qw(mail);    # specifies default mailer

         $mailer = Mail::Mailer->new;
         $mailer = Mail::Mailer->new($type, @args);

         $mailer->open(\%headers);
         print $mailer $body;
         $mailer->close
             or die "couldn't send whole message: $!\n";

DESCRIPTION

       Sends mail using any of the built-in methods.  As TYPE argument to new(), you can specify
       any of

       "sendmail"
           Use the "sendmail" program to deliver the mail.

       "smtp"
           Use the "smtp" protocol via Net::SMTP to deliver the mail. The server to use can be
           specified in @args with

            $mailer = Mail::Mailer->new('smtp', Server => $server);

           The smtp mailer does not handle "Cc" and "Bcc" lines, neither their "Resent-*"
           fellows. The "Debug" options enables debugging output from "Net::SMTP".

           [added 2.21] You may also use the "StartTLS => 1" options to upgrade the connection
           with STARTTLS.  You need "libnet" version 1.28 (2014) for this to work.

           You may also use the "Auth => [ $user, $password ]" option for SASL authentication. To
           make this work, you have to install the Authen::SASL distribution yourself: it is not
           automatically installed.

       "smtps"
           This option is deprecated when you have "libnet" 1.28 (2014) and above.

           Use the smtp over ssl protocol via Net::SMTP::SSL to deliver the mail.  Usage is
           identical to "smtp". You have to install Authen::SASL as well.

            $mailer = Mail::Mailer->new('smtps', Server => $server);

       "qmail"
           Use qmail's qmail-inject program to deliver the mail.

       "testfile"
           Used for debugging, this displays the data to the file named in
           $Mail::Mailer::testfile::config{outfile} which defaults to a file named
           "mailer.testfile".  No mail is ever sent.

       "Mail::Mailer" will search for executables in the above order. The default mailer will be
       the first one found.

METHODS

   Constructors
       Mail::Mailer->new($type, %options)
           The $type is one of the back-end sender implementations, as described in the
           DESCRIPTION chapter of this manual page.  The %options are passed to that back-end.

       $obj->open(HASH)
           The HASH consists of key and value pairs, the key being the name of the header field
           (eg, "To"), and the value being the corresponding contents of the header field.  The
           value can either be a scalar (eg, "gnat@frii.com") or a reference to an array of
           scalars ("eg, ['gnat@frii.com', 'Tim.Bunce@ig.co.uk']").

DETAILS

   ENVIRONMENT VARIABLES
       PERL_MAILERS
           Augments/override the build in choice for binary used to send out our mail messages.

           Format:

               "type1:mailbinary1;mailbinary2;...:type2:mailbinaryX;...:..."

           Example: assume you want you use private sendmail binary instead of mailx, one could
           set "PERL_MAILERS" to:

               "mail:/does/not/exists:sendmail:$HOME/test/bin/sendmail"

           On systems which may include ":" in file names, use "|" as separator between type-
           groups.

               "mail:c:/does/not/exists|sendmail:$HOME/test/bin/sendmail"

   BUGS
       Mail::Mailer does not help with folding, and does not protect against various web-script
       hacker attacks, for instance where a new-line is inserted in the content of the field.
