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.
Release Notes: Support was added for authenticating against a POP3 server before relaying a message to the SMTP server.
Release Notes: This version fixes a bug in the calls to the function that does PLAIN authentication.
Release Notes: This version integrates a patch to try different combinations of user, realm, and password in the plain authentication method. The class now tries other authentication methods if the previous ones do not succeed. The function to prepare message body data was fixed to work with all sorts of line break combinations. A test suite script is now provided to verify that the message body data is correctly prepared.
Release Notes: This release has the ability to specify a timeout value for how long the class should wait for data to be transferred between the SMTP server before giving up in error when the server is too slow to respond. An option to generate debug output formatted to show in HTML pages has been added.
Release Notes: A bug has been fixed in the regular expression that is used to escape message data lines starting with a dot (.).
