Some clients use "SSL" to mean the archaic smtps protocol (most famously
Outlook and Outlook Express) on port 465.
If you uncomment the smtps line in master.cf, you may see a difference.
Most modern clients, such as Squirelmail and Thunderbird, use STARTTLS
as one of their options when sending email.
