What::MTA(3)	      User Contributed Perl Documentation	  What::MTA(3)

NAME
       What::MTA - Find	out about running MTA

SYNOPSIS
	 $what = What->new(
		    Host => my.domain.org,
		    Port => 25,
		 );

	 $what->mta;
	 $what->mta_version;
	 $what->mta_banner;

DESCRIPTION
       What::MTA is a part of "What" package. It provides basic	information
       about running MTA: name,	version	and banner that	MTA prints out upon
       connection to it. It is not meant to be used directly, but via its
       interface, class	"What".	MTA's supported	are: Exim, Postfix (version
       only on localhost), Sendmail, Courier (name only), XMail, MaswMail.

       The What::MTA class is a	subclass of Net::Cmd and IO::Socket::INET.

CONSTRUCTOR
       new ( OPTIONS )
	   This	is the constructor for a new What object.

	   "OPTIONS" are passed	in a hash like fashion,	using key and value
	   pairs.  Possible options are:

	   Host	- is the name, or address, of the remote host to which a
	   connection to a running service is required to. It may be a single
	   scalar, as defined for the "PeerAddr" option	in IO::Socket::INET.
	   "Host" is optional, default value is	"localhost".

	   LocalAddr and LocalPort - These parameters are passed directly to
	   IO::Socket to allow binding the socket to a local port.

	   Timeout - Maximum time, in seconds, to wait for a response from the
	   server (default: 120)

	   Port	- Port to which	to connect to (default:	25)

	   Debug - Enable debugging information

       Example:

	   $what = What->new(
			      Host    => 'my.mail.domain'
			      Timeout => 30,
			      Debug   => 1,
			    );

	   $what = What->new(
			      Host => '10.10.10.1',
			      Port => 25,
			    );

METHODS
       mta()
	   Returns the name of the MTA running.

       mta_version()
	   Returns the version of the MTA running.

       mta_banner()
	   Returns the banner message which the	server replied with when the
	   initial connection was made.
