Mail::Mailer(3) Simple interface to electronic mailing mechanisms


   is a IO::Handle


use Mail::Mailer;
use Mail::Mailer qw(mail); # specifies default mailer
$mailer = Mail::Mailer->new;
$mailer = Mail::Mailer->new($type, @args);
print $mailer $body;
or die "couldn't send whole message: $!\n";


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

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.

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



Mail::Mailer->new(TYPE, ARGS)
The TYPE is one of the back-end sender implementations, as described in the DESCRIPTION chapter of this manual page. The ARGS are passed to that back-end.
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, "[email protected]") or a reference to an array of scalars ("eg, ['[email protected]', '[email protected]']").



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



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


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



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.


The MailTools bundle was developed by Graham Barr. Later, Mark Overmeer took over maintenance without commitment to further development.
