508*0Sstevel@tonic-gate=head1 NAME
509*0Sstevel@tonic-gate
510*0Sstevel@tonic-gateNet::SMTP - Simple Mail Transfer Protocol Client
511*0Sstevel@tonic-gate
512*0Sstevel@tonic-gate=head1 SYNOPSIS
513*0Sstevel@tonic-gate
514*0Sstevel@tonic-gate    use Net::SMTP;
515*0Sstevel@tonic-gate
516*0Sstevel@tonic-gate    # Constructors
517*0Sstevel@tonic-gate    $smtp = Net::SMTP->new('mailhost');
518*0Sstevel@tonic-gate    $smtp = Net::SMTP->new('mailhost', Timeout => 60);
519*0Sstevel@tonic-gate
520*0Sstevel@tonic-gate=head1 DESCRIPTION
521*0Sstevel@tonic-gate
522*0Sstevel@tonic-gateThis module implements a client interface to the SMTP and ESMTP
523*0Sstevel@tonic-gateprotocol, enabling a perl5 application to talk to SMTP servers. This
524*0Sstevel@tonic-gatedocumentation assumes that you are familiar with the concepts of the
525*0Sstevel@tonic-gateSMTP protocol described in RFC821.
526*0Sstevel@tonic-gate
527*0Sstevel@tonic-gateA new Net::SMTP object must be created with the I<new> method. Once
528*0Sstevel@tonic-gatethis has been done, all SMTP commands are accessed through this object.
529*0Sstevel@tonic-gate
530*0Sstevel@tonic-gateThe Net::SMTP class is a subclass of Net::Cmd and IO::Socket::INET.
531*0Sstevel@tonic-gate
532*0Sstevel@tonic-gate=head1 EXAMPLES
533*0Sstevel@tonic-gate
534*0Sstevel@tonic-gateThis example prints the mail domain name of the SMTP server known as mailhost:
535*0Sstevel@tonic-gate
536*0Sstevel@tonic-gate    #!/usr/local/bin/perl -w
537*0Sstevel@tonic-gate
538*0Sstevel@tonic-gate    use Net::SMTP;
539*0Sstevel@tonic-gate
540*0Sstevel@tonic-gate    $smtp = Net::SMTP->new('mailhost');
541*0Sstevel@tonic-gate    print $smtp->domain,"\n";
542*0Sstevel@tonic-gate    $smtp->quit;
543*0Sstevel@tonic-gate
544*0Sstevel@tonic-gateThis example sends a small message to the postmaster at the SMTP server
545*0Sstevel@tonic-gateknown as mailhost:
546*0Sstevel@tonic-gate
547*0Sstevel@tonic-gate    #!/usr/local/bin/perl -w
548*0Sstevel@tonic-gate
549*0Sstevel@tonic-gate    use Net::SMTP;
550*0Sstevel@tonic-gate
551*0Sstevel@tonic-gate    $smtp = Net::SMTP->new('mailhost');
552*0Sstevel@tonic-gate
553*0Sstevel@tonic-gate    $smtp->mail($ENV{USER});
554*0Sstevel@tonic-gate    $smtp->to('postmaster');
555*0Sstevel@tonic-gate
556*0Sstevel@tonic-gate    $smtp->data();
557*0Sstevel@tonic-gate    $smtp->datasend("To: postmaster\n");
558*0Sstevel@tonic-gate    $smtp->datasend("\n");
559*0Sstevel@tonic-gate    $smtp->datasend("A simple test message\n");
560*0Sstevel@tonic-gate    $smtp->dataend();
561*0Sstevel@tonic-gate
562*0Sstevel@tonic-gate    $smtp->quit;
563*0Sstevel@tonic-gate
564*0Sstevel@tonic-gate=head1 CONSTRUCTOR
565*0Sstevel@tonic-gate
566*0Sstevel@tonic-gate=over 4
567*0Sstevel@tonic-gate
568*0Sstevel@tonic-gate=item new Net::SMTP [ HOST, ] [ OPTIONS ]
569*0Sstevel@tonic-gate
570*0Sstevel@tonic-gateThis is the constructor for a new Net::SMTP object. C<HOST> is the
571*0Sstevel@tonic-gatename of the remote host to which an SMTP connection is required.
572*0Sstevel@tonic-gate
573*0Sstevel@tonic-gateIf C<HOST> is an array reference then each value will be attempted
574*0Sstevel@tonic-gatein turn until a connection is made.
575*0Sstevel@tonic-gate
576*0Sstevel@tonic-gateIf C<HOST> is not given, then the C<SMTP_Host> specified in C<Net::Config>
577*0Sstevel@tonic-gatewill be used.
578*0Sstevel@tonic-gate
579*0Sstevel@tonic-gateC<OPTIONS> are passed in a hash like fashion, using key and value pairs.
580*0Sstevel@tonic-gatePossible options are:
581*0Sstevel@tonic-gate
582*0Sstevel@tonic-gateB<Hello> - SMTP requires that you identify yourself. This option
583*0Sstevel@tonic-gatespecifies a string to pass as your mail domain. If not
584*0Sstevel@tonic-gategiven a guess will be taken.
585*0Sstevel@tonic-gate
586*0Sstevel@tonic-gateB<LocalAddr> and B<LocalPort> - These parameters are passed directly
587*0Sstevel@tonic-gateto IO::Socket to allow binding the socket to a local port.
588*0Sstevel@tonic-gate
589*0Sstevel@tonic-gateB<Timeout> - Maximum time, in seconds, to wait for a response from the
590*0Sstevel@tonic-gateSMTP server (default: 120)
591*0Sstevel@tonic-gate
592*0Sstevel@tonic-gateB<ExactAddresses> - If true the all ADDRESS arguments must be as
593*0Sstevel@tonic-gatedefined by C<addr-spec> in RFC2822. If not given, or false, then
594*0Sstevel@tonic-gateNet::SMTP will attempt to extract the address from the value passed.
595*0Sstevel@tonic-gate
596*0Sstevel@tonic-gateB<Debug> - Enable debugging information
597*0Sstevel@tonic-gate
598*0Sstevel@tonic-gate
599*0Sstevel@tonic-gateExample:
600*0Sstevel@tonic-gate
601*0Sstevel@tonic-gate
602*0Sstevel@tonic-gate    $smtp = Net::SMTP->new('mailhost',
603*0Sstevel@tonic-gate			   Hello => 'my.mail.domain'
604*0Sstevel@tonic-gate			   Timeout => 30,
605*0Sstevel@tonic-gate                           Debug   => 1,
606*0Sstevel@tonic-gate			  );
607*0Sstevel@tonic-gate
608*0Sstevel@tonic-gate=back
609*0Sstevel@tonic-gate
610*0Sstevel@tonic-gate=head1 METHODS
611*0Sstevel@tonic-gate
612*0Sstevel@tonic-gateUnless otherwise stated all methods return either a I<true> or I<false>
613*0Sstevel@tonic-gatevalue, with I<true> meaning that the operation was a success. When a method
614*0Sstevel@tonic-gatestates that it returns a value, failure will be returned as I<undef> or an
615*0Sstevel@tonic-gateempty list.
616*0Sstevel@tonic-gate
617*0Sstevel@tonic-gate=over 4
618*0Sstevel@tonic-gate
619*0Sstevel@tonic-gate=item banner ()
620*0Sstevel@tonic-gate
621*0Sstevel@tonic-gateReturns the banner message which the server replied with when the
622*0Sstevel@tonic-gateinitial connection was made.
623*0Sstevel@tonic-gate
624*0Sstevel@tonic-gate=item domain ()
625*0Sstevel@tonic-gate
626*0Sstevel@tonic-gateReturns the domain that the remote SMTP server identified itself as during
627*0Sstevel@tonic-gateconnection.
628*0Sstevel@tonic-gate
629*0Sstevel@tonic-gate=item hello ( DOMAIN )
630*0Sstevel@tonic-gate
631*0Sstevel@tonic-gateTell the remote server the mail domain which you are in using the EHLO
632*0Sstevel@tonic-gatecommand (or HELO if EHLO fails).  Since this method is invoked
633*0Sstevel@tonic-gateautomatically when the Net::SMTP object is constructed the user should
634*0Sstevel@tonic-gatenormally not have to call it manually.
635*0Sstevel@tonic-gate
636*0Sstevel@tonic-gate=item etrn ( DOMAIN )
637*0Sstevel@tonic-gate
638*0Sstevel@tonic-gateRequest a queue run for the DOMAIN given.
639*0Sstevel@tonic-gate
640*0Sstevel@tonic-gate=item auth ( USERNAME, PASSWORD )
641*0Sstevel@tonic-gate
642*0Sstevel@tonic-gateAttempt SASL authentication.
643*0Sstevel@tonic-gate
644*0Sstevel@tonic-gate=item mail ( ADDRESS [, OPTIONS] )
645*0Sstevel@tonic-gate
646*0Sstevel@tonic-gate=item send ( ADDRESS )
647*0Sstevel@tonic-gate
648*0Sstevel@tonic-gate=item send_or_mail ( ADDRESS )
649*0Sstevel@tonic-gate
650*0Sstevel@tonic-gate=item send_and_mail ( ADDRESS )
651*0Sstevel@tonic-gate
652*0Sstevel@tonic-gateSend the appropriate command to the server MAIL, SEND, SOML or SAML. C<ADDRESS>
653*0Sstevel@tonic-gateis the address of the sender. This initiates the sending of a message. The
654*0Sstevel@tonic-gatemethod C<recipient> should be called for each address that the message is to
655*0Sstevel@tonic-gatebe sent to.
656*0Sstevel@tonic-gate
657*0Sstevel@tonic-gateThe C<mail> method can some additional ESMTP OPTIONS which is passed
658*0Sstevel@tonic-gatein hash like fashion, using key and value pairs.  Possible options are:
659*0Sstevel@tonic-gate
660*0Sstevel@tonic-gate Size        => <bytes>
661*0Sstevel@tonic-gate Return      => "FULL" | "HDRS"
662*0Sstevel@tonic-gate Bits        => "7" | "8" | "binary"
663*0Sstevel@tonic-gate Transaction => <ADDRESS>
664*0Sstevel@tonic-gate Envelope    => <ENVID>
665*0Sstevel@tonic-gate
666*0Sstevel@tonic-gateThe C<Return> and C<Envelope> parameters are used for DSN (Delivery
667*0Sstevel@tonic-gateStatus Notification).
668*0Sstevel@tonic-gate
669*0Sstevel@tonic-gate=item reset ()
670*0Sstevel@tonic-gate
671*0Sstevel@tonic-gateReset the status of the server. This may be called after a message has been
672*0Sstevel@tonic-gateinitiated, but before any data has been sent, to cancel the sending of the
673*0Sstevel@tonic-gatemessage.
674*0Sstevel@tonic-gate
675*0Sstevel@tonic-gate=item recipient ( ADDRESS [, ADDRESS [ ...]] [, OPTIONS ] )
676*0Sstevel@tonic-gate
677*0Sstevel@tonic-gateNotify the server that the current message should be sent to all of the
678*0Sstevel@tonic-gateaddresses given. Each address is sent as a separate command to the server.
679*0Sstevel@tonic-gateShould the sending of any address result in a failure then the
680*0Sstevel@tonic-gateprocess is aborted and a I<false> value is returned. It is up to the
681*0Sstevel@tonic-gateuser to call C<reset> if they so desire.
682*0Sstevel@tonic-gate
683*0Sstevel@tonic-gateThe C<recipient> method can some additional OPTIONS which is passed
684*0Sstevel@tonic-gatein hash like fashion, using key and value pairs.  Possible options are:
685*0Sstevel@tonic-gate
686*0Sstevel@tonic-gate Notify    =>
687*0Sstevel@tonic-gate SkipBad   => ignore bad addresses
688*0Sstevel@tonic-gate
689*0Sstevel@tonic-gateIf C<SkipBad> is true the C<recipient> will not return an error when a
690*0Sstevel@tonic-gatebad address is encountered and it will return an array of addresses
691*0Sstevel@tonic-gatethat did succeed.
692*0Sstevel@tonic-gate
693*0Sstevel@tonic-gate  $smtp->recipient($recipient1,$recipient2);  # Good
694*0Sstevel@tonic-gate  $smtp->recipient($recipient1,$recipient2, { SkipBad => 1 });  # Good
695*0Sstevel@tonic-gate  $smtp->recipient("$recipient,$recipient2"); # BAD
696*0Sstevel@tonic-gate
697*0Sstevel@tonic-gate=item to ( ADDRESS [, ADDRESS [...]] )
698*0Sstevel@tonic-gate
699*0Sstevel@tonic-gate=item cc ( ADDRESS [, ADDRESS [...]] )
700*0Sstevel@tonic-gate
701*0Sstevel@tonic-gate=item bcc ( ADDRESS [, ADDRESS [...]] )
702*0Sstevel@tonic-gate
703*0Sstevel@tonic-gateSynonyms for C<recipient>.
704*0Sstevel@tonic-gate
705*0Sstevel@tonic-gate=item data ( [ DATA ] )
706*0Sstevel@tonic-gate
707*0Sstevel@tonic-gateInitiate the sending of the data from the current message.
708*0Sstevel@tonic-gate
709*0Sstevel@tonic-gateC<DATA> may be a reference to a list or a list. If specified the contents
710*0Sstevel@tonic-gateof C<DATA> and a termination string C<".\r\n"> is sent to the server. And the
711*0Sstevel@tonic-gateresult will be true if the data was accepted.

738*0Sstevel@tonic-gateNet::SMTP attempts to DWIM with addresses that are passed. For
739*0Sstevel@tonic-gateexample an application might extract The From: line from an email
740*0Sstevel@tonic-gateand pass that to mail(). While this may work, it is not reccomended.
741*0Sstevel@tonic-gateThe application should really use a module like L<Mail::Address>
742*0Sstevel@tonic-gateto extract the mail address and pass that.

746*0Sstevel@tonic-gateaccept accept the address surrounded by angle brackets.
