. 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
-
Returns the banner message which the server replied with when the initial connection was made.
