--- Comment #1 from Pierre Fortin <pf at pfortin.com> ---
Testing with gmail.com, discovered:

All my GMail accounts are setup as:
 POP3S(995), SMTP(465) & they work with SSL; but SMTP fails with STARTTLS

So I was setting up new accounts based on past history...

Setting up a new CM testing instance, discovered that GMail has apparently made
a port change (or started using DNS SRV) such that auto-configure sets:
 POP3S(995) & SMTP(587)

However, after testing {465,587} v. {SSL,STARTTLS}, GMail only accepts:
  465 SSL
  587 STARTTLS
the others fail with:
### SMTP 465 STARTTLS
* Account 'xxx at gmail.com': Connecting to SMTP server: smtp.gmail.com:465...
*** Connection closed by the remote host.
### SMTP 587 SSL
* Account 'xxx at gmail.com': Connecting to SMTP server: smtp.gmail.com:587...
*** SSL handshake failed
*** Error occurred while sending the message.

Servers can pick whatever ports they want and define SSL, STARTTLS or both; so
I don't see where it would be possible to use predefined defaults.

Suggest the wizard try to avoid config issues by testing the offered port
capabilities as appears to be outlined in 
https://tools.ietf.org/html/rfc6186#section-4
