STARTTLS uses the normal IMAP Port 143
SSL uses the IMAPS Port 993

so you have to use '{localhost:143/imap/tls}'
or '{localhost:993/imap/ssl}'

If you have still have problems you might try to add the
option "novalidate-cert" to ignore certificate validation errors.
But in normal operation you should fix the validation instead of
ignoring the errors
