-=item new Net::SMTP [ HOST, ] [ OPTIONS ]
+=item new ( [ HOST ] [, OPTIONS ] )
This is the constructor for a new Net::SMTP object. C<HOST> is the
name of the remote host to which an SMTP connection is required.
-If C<HOST> is an array reference then each value will be attempted
-in turn until a connection is made.
-
-If C<HOST> is not given, then the C<SMTP_Host> specified in C<Net::Config>
-will be used.
+C<HOST> is optional. If C<HOST> is not given then it may instead be
+passed as the C<Host> option described below. If neither is given then
+the C<SMTP_Hosts> specified in C<Net::Config> will be used.
C<OPTIONS> are passed in a hash like fashion, using key and value pairs.
Possible options are:
B<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.
+specifies a string to pass as your mail domain. If not given localhost.localdomain
+will be used.
+
+B<Host> - SMTP host to connect to. It may be a single scalar, as defined for
+the C<PeerAddr> option in L<IO::Socket::INET>, or a reference to
+an array with hosts to try in turn. The L</host> method will return the value
+which was used to connect to the host.
B<LocalAddr> and B<LocalPort> - These parameters are passed directly
to IO::Socket to allow binding the socket to a local port.

=head1 METHODS
automatically when the Net::SMTP object is constructed the user should
normally not have to call it manually.
+=item host ()
+
+Returns the value used by the constructor, and passed to IO::Socket::INET,
+to connect to the host.
+
=item etrn ( DOMAIN )
Request a queue run for the DOMAIN given.
Bits => "7" | "8" | "binary"
Transaction => <ADDRESS>
Envelope => <ENVID>
+ XVERP => 1
The C<Return> and C<Envelope> parameters are used for DSN (Delivery
Status Notification).
initiated, but before any data has been sent, to cancel the sending of the
message.
-=item recipient ( ADDRESS [, ADDRESS [ ...]] [, OPTIONS ] )
+=item 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 I<false> value is returned. It is up to the
-user to call C<reset> if they so desire.

+The C<recipient> method can also pass additional case-sensitive OPTIONS as an
+anonymous hash using key and value pairs. Possible options are:
- Notify =>
- SkipBad => ignore bad addresses
+ Notify => ['NEVER'] or ['SUCCESS','FAILURE','DELAY'] (see below)
+ SkipBad => 1 (to ignore bad addresses)
-If C<SkipBad> is true the C<recipient> will not return an error when a
-bad address is encountered and it will return an array of addresses
-that did succeed.
+If C<SkipBad> is true the C<recipient> will not return an error when a bad

$smtp->recipient($recipient1,$recipient2); # Good
$smtp->recipient($recipient1,$recipient2, { SkipBad => 1 }); # Good
- $smtp->recipient("$recipient,$recipient2"); # BAD
+ $smtp->recipient($recipient1,$recipient2, { Notify => ['FAILURE','DELAY'], SkipBad => 1 }); # Good
+ @goodrecips=$smtp->recipient(@recipients, { Notify => ['FAILURE'], SkipBad => 1 }); # Good
+ $smtp->recipient("$recipient,$recipient2"); # BAD
+
+Notify is used to request Delivery Status Notifications (DSNs), but your
+SMTP/ESMTP service may not respect this request depending upon its version and
+your site's SMTP configuration.
+
+Leaving out the Notify option usually defaults an SMTP service to its default
+behavior equivalent to ['FAILURE'] notifications only, but again this may be
+dependent upon your site's SMTP configuration.
+
+The NEVER keyword must appear by itself if used within the Notify option and "requests
+that a DSN not be returned to the sender under any conditions."
+
+ {Notify => ['NEVER']}
+
+ $smtp->recipient(@recipients, { Notify => ['NEVER'], SkipBad => 1 }); # Good
+
+You may use any combination of these three values 'SUCCESS','FAILURE','DELAY' in
+the anonymous array reference as defined by RFC3461 (see http://rfc.net/rfc3461.html
+for more information. Note: quotations in this topic from same.).
+
+A Notify parameter of 'SUCCESS' or 'FAILURE' "requests that a DSN be issued on
+successful delivery or delivery failure, respectively."
+
+A Notify parameter of 'DELAY' "indicates the sender's willingness to receive
+delayed DSNs. Delayed DSNs may be issued if delivery of a message has been
+delayed for an unusual amount of time (as determined by the Message Transfer
+Agent (MTA) at which the message is delayed), but the final delivery status
+(whether successful or failure) cannot be determined. The absence of the DELAY
+keyword in a NOTIFY parameter requests that a "delayed" DSN NOT be issued under
+any conditions."
+
+ {Notify => ['SUCCESS','FAILURE','DELAY']}
+
+ $smtp->recipient(@recipients, { Notify => ['FAILURE','DELAY'], SkipBad => 1 }); # Good
=item to ( ADDRESS [, ADDRESS [...]] )
Verify that C<ADDRESS> is a legitimate mailing address.
+Most sites usually disable this feature in their SMTP service configuration.
+Use "Debug => 1" option under new() to see if disabled.
+
=item help ( [ $subject ] )
Request help text from the server. Returns the text or undef upon failure
