But, if they've hacked smtps then they've also hacked submission; right?

Hi,
I had an email account password guessed through auth attempts via smtps.
I did not realize this as I had forgotten I had it enabled at all. I
was looking at the submission log and scratching my head not
understanding how messages got to the remote queue without anything in
the submission log, until I realized smpts was enabled and it was
logging to /var/log/maillog and not to any log under /var/log/qmail...
My first question: is it safe to disable smtps, I guess I don't need
it for anything as all my users should be using 587/submission instead?
Second question: How do I disable it? Should I just
remove /var/qmail/supervise/smtps/run file? And/or block it at
firewall level?
Third question: to prevent brute force attacks, is fail2ban the best
option to do it? I just follow the instructions at
http://www.qmailtoaster.com/fail2ban.html ?
Best,
Peter
