.SH DESCRIPTION
.IX Header "DESCRIPTION"
Sends mail using any of the built-in methods.  As TYPE argument
to \fBnew()\fR, you can specify any of
.ie n .IP """sendmail""" 4
.el .IP \f(CWsendmail\fR 4
.IX Item "sendmail"
Use the \f(CW\*(C`sendmail\*(C'\fR program to deliver the mail.
.ie n .IP """smtp""" 4
.el .IP \f(CWsmtp\fR 4
.IX Item "smtp"
Use the \f(CW\*(C`smtp\*(C'\fR protocol via Net::SMTP to deliver the mail. The server
to use can be specified in \f(CW@args\fR with
.Sp
.Vb 1
\& $mailer = Mail::Mailer\->new(\*(Aqsmtp\*(Aq, Server => $server);
.Ve
.Sp
The smtp mailer does not handle \f(CW\*(C`Cc\*(C'\fR and \f(CW\*(C`Bcc\*(C'\fR lines, neither their
\&\f(CW\*(C`Resent\-*\*(C'\fR fellows. The \f(CW\*(C`Debug\*(C'\fR options enables debugging output
from \f(CW\*(C`Net::SMTP\*(C'\fR.
.Sp
[added 2.21] You may also use the \f(CW\*(C`StartTLS => 1\*(C'\fR options to upgrade the
connection with STARTTLS.  You need \f(CW\*(C`libnet\*(C'\fR version 1.28 (2014) for this
to work.
.Sp
You may also use the \f(CW\*(C`Auth => [ $user, $password ]\*(C'\fR option for SASL
authentication. To make this work, you have to install the Authen::SASL
distribution yourself: it is not automatically installed.
.ie n .IP """smtps""" 4
.el .IP \f(CWsmtps\fR 4
.IX Item "smtps"
This option is \fBdeprecated\fR when you have \f(CW\*(C`libnet\*(C'\fR 1.28 (2014) and above.
.Sp
Use the smtp over ssl protocol via Net::SMTP::SSL to deliver the mail.
Usage is identical to \f(CW\*(C`smtp\*(C'\fR. You have to install Authen::SASL as
well.
.Sp
.Vb 1
\& $mailer = Mail::Mailer\->new(\*(Aqsmtps\*(Aq, Server => $server);
.Ve
.ie n .IP """qmail""" 4
.el .IP \f(CWqmail\fR 4
.IX Item "qmail"
Use qmail's qmail-inject program to deliver the mail.
.ie n .IP """testfile""" 4
.el .IP \f(CWtestfile\fR 4
.IX Item "testfile"
Used for debugging, this displays the data to the file named in
\&\f(CW$Mail::Mailer::testfile::config{outfile}\fR which defaults to a file
named \f(CW\*(C`mailer.testfile\*(C'\fR.  No mail is ever sent.
.PP
\&\f(CW\*(C`Mail::Mailer\*(C'\fR will search for executables in the above order. The
default mailer will be the first one found.

.ie n .IP "Mail::Mailer\->\fBnew\fR($type, %options)" 4
.el .IP "Mail::Mailer\->\fBnew\fR($type, \f(CW%options\fR)" 4
.IX Item "Mail::Mailer->new($type, %options)"
The \f(CW$type\fR is one of the back-end sender implementations, as described in
the DESCRIPTION chapter of this manual page.  The \f(CW%options\fR are passed to
that back-end.
.ie n .IP $obj\->\fBopen\fR(HASH) 4
.el .IP \f(CW$obj\fR\->\fBopen\fR(HASH) 4
.IX Item "$obj->open(HASH)"
The HASH consists of key and value pairs, the key being the name of
the header field (eg, \f(CW\*(C`To\*(C'\fR), and the value being the corresponding
contents of the header field.  The value can either be a scalar
(eg, \f(CW\*(C`gnat@frii.com\*(C'\fR) or a reference to an array of scalars
(\f(CW\*(C`eg, [\*(Aqgnat@frii.com\*(Aq, \*(AqTim.Bunce@ig.co.uk\*(Aq]\*(C'\fR).

Augments/override the build in choice for binary used to send out

Format:
.Sp
.Vb 1
\&    "type1:mailbinary1;mailbinary2;...:type2:mailbinaryX;...:..."
.Ve
.Sp
Example: assume you want you use private sendmail binary instead
of mailx, one could set \f(CW\*(C`PERL_MAILERS\*(C'\fR to:
.Sp
.Vb 1
\&    "mail:/does/not/exists:sendmail:$HOME/test/bin/sendmail"
.Ve
.Sp
On systems which may include \f(CW\*(C`:\*(C'\fR in file names, use \f(CW\*(C`|\*(C'\fR as separator
between type-groups.

.Vb 1
\&    "mail:c:/does/not/exists|sendmail:$HOME/test/bin/sendmail"

.SS BUGS
.IX Subsection "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.
