All,

To scratch an itch, I've written some code against the SVN codebase (rev 362) to connect to SMTP servers that use STARTTLS. This ought to resolve ticket #1483813 (or at least it does for me).

Briefly, I've:

Added main.inc.php::$rcmail_config['smtp_starttls'] to control use of STARTTLS

Modified rcube_smtp.inc::smtp_mail() to check configuration variable and try STARTTLS if set

Modified Net_SMTP::Net_SMTP() to accept an optional param indicating if STARTTLS should be used. Modified Net_SMTP::connect() to establish and negotiate TLS session if using STARTTLS. Added Net_SMTP::_starttls() to attempt TLS handshake and establish secure connection.

Added Net_Socket::enableCrypto() to turn encryption on/off on the socket.

Caveats:

This relies on functionality only available in PHP 5.1.0rc1 (with OpenSSL support) and higher. The code checks for a suitable environment but I appreciate that this is higher than the minimum PHP requirements listed on your wiki.

It's been a little while (about two years) since I last wrote any php code so it isn't as polished as I'd like.

If a developer is interested in the code, please let me know how to get it to you.

Oh, and thanks for such great software. It says a lot that it was worth my while to roll up my sleeves and add support for a personal show stopper rather than switch to a different webmail client!

Regards,

Matt
