Mail::Mailer(3)

NAME
Mail::Mailer - Simple interface to electronic mailing mechanisms

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

    $mailer = new Mail::Mailer;

    $mailer = new Mail::Mailer $type, @args;

    $mailer->open(\%headers);

    print $mailer $body;

    $mailer->close;

DESCRIPTION
Sends mail using any of the built-in methods. As $type 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 = new Mail::Mailer '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 (requires Authen::SASL and MIME::Base64).

"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.

  ARGUMENTS
"new" can optionally be given a $type, which is one "sendmail", "mail", ... given above.

"open" is given a reference to a 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']").

TO DO
Assist formatting of fields in ...::rfc822:send_headers to ensure valid in the face of newlines and longlines etc.

Secure all forms of send_headers() against hacker attack and invalid contents. Especially "\n~..." in ...::mail::send_headers.

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"
