- 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
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.
- 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
PeerAddr option in IO::Socket::INET.
Host is 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 name of the MTA running.
Returns the version of the MTA running.
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.
