- EXAMPLES OF MTA BANNERS
What::MTA - Find out about running MTA
$what = What->new( Host => my.domain.org, Port => 25, ); $what->mta; $what->mta_version; $what->mta_banner;
What::MTA is a part of
Whatpackage. 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.
- new ( OPTIONS )
This is the constructor for a new What object.
OPTIONSare 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
PeerAddroption in IO::Socket::INET.
Hostis optional, default value is
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
$what = What->new( Host => 'my.mail.domain' Timeout => 30, Debug => 1, ); $what = What->new( Host => '10.10.10.1', Port => 25, );
Returns the banner message which the server replied with when the initial connection was made.

Lot of code taken from Net::Cmd, without which this class probably wouldn't have been written.
