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_version()
