Net::LMTP - Local Mail Transfer Protocol Client
use Net::LMTP;
# Constructors
$lmtp = Net::LMTP->new('mailhost', 2003);
$lmtp = Net::LMTP->new('mailhost', 2003, Timeout => 60);
This module implements a client interface to the LMTP protocol, enabling a perl5
application to talk to LMTP servers. This documentation assumes that you are
familiar with the concepts of the LMTP protocol described in RFC2033. This
module is based on Net::SMTP and shares more than %95
of its code with Net::SMTP.
A new Net::LMTP object must be created with the new method.
Once this has been done, all LMTP commands are accessed through this
object.
The Net::LMTP class is a subclass of Net::Cmd and
IO::Socket::INET.
Net::LMTP does not yet implement full implementation of the
protocol as specified in RFC2033. In particular, handling per-recipient
reply codes from the DATA command is not yet implemented. Net::LMTP can
still be used to deliver to multiple recipients, but you will not be able to
get the DATA reply code for each recipient.
This example prints the mail domain name of the LMTP server known as mailboxhost
with LMTP service on port 2003:
#!/usr/local/bin/perl -w
use Net::LMTP;
my $lmtp = Net::LMTP->new('mailboxhost', 2003);
print $lmtp->domain,"\n";
$lmtp->quit;
This example sends a small message to the postmaster at the SMTP
server known as mailhost:
#!/usr/local/bin/perl -w
use Net::LMTP;
my $lmtp = Net::LMTP->new('mailboxhost', 2003);
$lmtp->mail($ENV{USER});
$lmtp->to('postmaster');
$lmtp->data();
$lmtp->datasend("To: postmaster\n");
$lmtp->datasend("\n");
$lmtp->datasend("A simple test message\n");
$lmtp->dataend();
$lmtp->quit;
- new Net::LMTP HOST, PORT [, OPTIONS ]
- This is the constructor for a new Net::LMTP object.
"HOST" is the name of the remote host to
which a LMTP connection is required.
"PORT" is the port on which the LMTP
service is running. Both of these arguments are required.
"OPTIONS" are passed in a
hash like fashion, using key and value pairs. Possible options are:
Hello - SMTP requires that you identify yourself. This
option specifies a string to pass as your mail domain. If not given a
guess will be taken.
Timeout - Maximum time, in seconds, to wait for a
response from the SMTP server (default: 120)
Debug - Enable debugging information
Example:
$lmtp = Net::SMTP->new('mailboxhost',2003,
Hello => 'my.mail.domain'
Timeout => 30,
Debug => 1,
);
Unless otherwise stated all methods return either a true or false
value, with true meaning that the operation was a success. When a
method states that it returns a value, failure will be returned as
undef or an empty list.
- banner ()
- Returns the banner message which the server replied with when the initial
connection was made.
- domain ()
- Returns the domain that the remote LMTP server identified itself as during
connection.
- hello ( DOMAIN )
- Tell the remote server the mail domain which you are in using the LHLO
command. Since this method is invoked automatically when the Net::LMTP
object is constructed the user should normally not have to call it
manually.
- etrn ( DOMAIN )
- Request a queue run for the DOMAIN given.
- mail ( ADDRESS [, OPTIONS] )
- send ( ADDRESS )
- send_or_mail ( ADDRESS )
- send_and_mail ( ADDRESS )
- Send the appropriate command to the server MAIL, SEND, SOML or SAML.
"ADDRESS" is the address of the sender.
This initiates the sending of a message. The method
"recipient" should be called for each
address that the message is to be sent to.
The "mail" method can some
additional ESMTP OPTIONS which is passed in hash like fashion, using key
and value pairs. Possible options are:
Size => <bytes>
Return => <???>
Bits => "7" | "8"
Transaction => <ADDRESS>
Envelope => <ENVID>
- reset ()
- Reset the status of the server. This may be called after a message has
been initiated, but before any data has been sent, to cancel the sending
of the message.
- recipient ( ADDRESS [, ADDRESS [ ...]] [, OPTIONS ] )
- Notify the server that the current message should be sent to all of the
addresses given. Each address is sent as a separate command to the server.
Should the sending of any address result in a failure then the process is
aborted and a false value is returned. It is up to the user to call
"reset" if they so desire.
The "recipient" method can
some additional OPTIONS which is passed in hash like fashion, using key
and value pairs. Possible options are:
Notify =>
SkipBad => ignore bad addresses
If "SkipBad" is true the
"recipient" will not return an error
when a bad address is encountered and it will return an array of
addresses that did succeed.
- to ( ADDRESS [, ADDRESS [...]] )
- A synonym for "recipient".
- data ( [ DATA ] )
- Initiate the sending of the data from the current message.
"DATA" may be a reference to
a list or a list. If specified the contents of
"DATA" and a termination string
".\r\n" is sent to the server. And the
result will be true if the data was accepted.
If "DATA" is not specified
then the result will indicate that the server wishes the data to be
sent. The data must then be sent using the
"datasend" and
"dataend" methods described in
Net::Cmd.
- expand ( ADDRESS )
- Request the server to expand the given address Returns an array which
contains the text read from the server.
- verify ( ADDRESS )
- Verify that "ADDRESS" is a legitimate
mailing address.
- help ( [ $subject ] )
- Request help text from the server. Returns the text or undef upon
failure
- quit ()
- Send the QUIT command to the remote SMTP server and close the socket
connection.
