This class inherit from Net::Server::Mail::ESMTP. Please see
Net::Server::Mail::ESMTP for documentation of common methods.
.SH "EVENTS"
.IX Header "EVENTS"
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.
