Net::Server::Mail::LMTP - A module to implement the LMTP protocole

This class implement the LMTP (RFC 2033) protocol.

This class inherit from Net::Server::Mail::ESMTP. Please see Net::Server::Mail::ESMTP for documentation of common methods.

Descriptions of callback who's can be used with set_callback method. All handle takes the Net::Server::Mail::ESMTP object as first argument and specific callback's arguments.

Same as ESMTP EHLO, please see Net::Server::Mail::ESMTP.

Overide the default DATA event by a per recipient response. It will be called for each recipients with data (in a scalar reference) as first argument followed by the current recipient.

Please, see Net::Server::Mail, Net::Server::Mail::SMTP and Net::Server::Mail::ESMTP.
