STARTTLS over port 587

We want to get all our end-users to switch over to using POP3/995, IMAP/993 & SMTP/STARTover port 587 by year's end. Is there a way to get a list of clients using historical methods POP/110, IMAP/143, SMTP/25,465,2525,8888 etc ? I want to start sending out notices that target the clients that need to change their configurations rather than targeting all users. At some point, we'll need to pick up the phone and beg :-)

  Hello John, I recommend replicating the specific conditions you are looking for while logging in with a test email account, and monitoring the following log files when doing so:
  /var/log/exim_mainlog /var/log/maillog
  Then, access the email account securely and note any differences in the above log files. You can then search those log files for entries specific to the non-secure logins. EX:
  grep "method=PLAIN" /var/log/maillog
  Thank you.
