[MlMt] IMAP Port logic

Following a close look at our mailserver due to an “attack”, we want to better understand how MM decides which port to use to open a connection.
Port 143 – this is the default IMAP non-encrypted port;
Port 993 – this is the port you need to use if you want to connect using IMAP securely
We noticed that although “Require SSL” is selected, MM tries to connect on port 143, where we would have expected that port 993 would be used.
Thanks in advance for any guidance,
