how to get IMP to STARTTLS

[Curtis Doty]

Runnung IMAP4rev1 which advertises:

	[CAPABILITY IMAP4REV1 LOGIN-REFERRALS STARTTLS LOGINDISABLED]

The requirement being: no clear text passwords.

But tried a dozen combinations on 'protocol' => 'yada/yada' to no avail.

	/imaprev1 /tls /secure /novalidate-cert etc.

It appears to either a) go straight into ssl mode and hang (on port 143
mind you, not 993!!), or b) it will immediately issue a LOGOUT.

Does IMP3.0/PHP4.1.2 even know how to STARTTLS? Or am I just editing the
config wrong?

I'd really appreciate an example or hints on how to debug. Setting
LOG_DEBUG in horde.php doesn't tell much until after the fact.
