I think non http based would be something like an instant message.

Sure; TLS is available with a wide variety of protocols, each of the following have a -S variant:

SMTP
POP3
IMAP
LDAP

Dave,

What makes those "ssl traffic"

Dave HoweCommented:
trojan: each has an explicit ssl (different port) variant.

SMTP explicit (SMTPS) can be found on port 465 instead of 25/587
POP3 explicit (POP3S)  can be found on port 995 instead of 110
IMAP explicit (IMAPS) can be found on port 993 instead of 143
LDAP explicit (LDAPS) can be found on port 636 instead of 389

this is exactly the same as the way that HTTP explicit (HTTPS) can be found on 443 instead of 80 :)

in most cases, now that TLS has supplanted SSL, it is expected that you use the implicit mode (i.e. connect to the non-ssl port, and issue a STARTTLS command to begin encryption) but the above are still well-supported in most clients.
