Okay, here you go:
Evolution 1.4.5
- SMTPS first
- STARTTLS if SMTPS failed
Mozilla 1.4
- STARTTLS only
Outlook & Outlook Express 6
- STARTTLS if port 25 entered
- SMTPS if any other port entered
Kmail 1.5.1
- STARTTLS if selected SSL
- SMTPS if selected TLS
I found out these using a sendmail daemon listening on port 25, doing
TLS and an stunnel process doing SMTPS, listening on port 465.
Hope this will help you to hack something up :)
Thanks
