Release Notes: This release adds support for connecting to the SMTP server via SOCKS servers or HTTP proxy servers.
Release Notes: This release added support to start TLS encryption protocol after the connection is started, so it can work for sending messages via the Hotmail SMTP server. Documentation of the class reference manual was added.
Release Notes: Support was added for sending messages to SMTP servers that require secure connections using SSL, like Gmail. The class now ignores the error when the server disconnects without responding to the final QUIT command.
Release Notes: The SASL client library class is now used to perform authentication with all the mechanisms supported by that library, such as PLAIN, LOGIN, CRAM-MD5, NTLM (Windows or Linux/Unix with Samba), and others.
Release Notes: A bug where the SMTP authentication step was skipped if the first authentication method declared by the server was not yet supported by the class was fixed.
