That might be OK for port 587, but not for 465. SMTP is a plain text protocol, until TLS is negotiated by STARTTLS. Port 465 is SMTP over TLS, and launches straight into SSL/TLS before anything else.
OTOH, it works perfectly fine for my Netscape 7.1 (on the same system) with both AUTH CRAM-MD5 and SSL/TLS
With all ports? Hard to believe...
