Hi Paul ---Paul wrote--- SquirrelMail supports STARTTLS. If I recall correctly, you set $use_smtp_tls to 2 in config.php --- But I only has changed the communication to the SMTP-server via the administrative plugin to "STARTTLS". Will this plugin change the settings in the config.php file? Is my understanding about TLS and STARTTLS correct (see my understanding below)? "As I have understand the difference between STARTTLS and TLS, STARTTLS is a protocol where the client, e.g. SquirrelMail, first communicate over an unsecure connection, but after that communicate over TLS, because STARTTLS tell SquirrelMail that the server can communicate over TLS. When I select the TLS-option in the SquirrelMail interface, SquirrelMail and other applications, require a "directly" TLS-connection via another port number, e.g. 465". --- Thanks in advance for your answer, and have a nice day.
