libESMTP 1.0.6+

libESMTP is an SMTP client library intended for software developers. It manages submission of electronic mail via a preconfigured Mail Transport Agent (MTA) such as Exim or Postfix. libESMTP offloads the developer of the need to handle the complexity of negotiating the SMTP protocol by providing a simple API. Additionally libESMTP transparently handles many SMTP extensions including authentication. This is the original libESMTP software previously hosted on and managed by the original author.
