I've tried the changes that I put below. Users are still able to log in from the LAN.
However, despite putting the appropriate rule in my firewall allowing port 143 I cannot create a user on a PC outside my network.
I'm using Thunderbird to do the testing. Is there a better way to test my setup? Thunderbird doesn't give any diagnostic data, it just says it's failed to test the account.
Connect with:
openssl s_client -connect <your server IP address>:143 -starttls imap
Then issue IMAP commands:
01 CAPABILITY 02 LOGIN user password 03 LOGOUT
That should be successful and you should have seen the configured AUTH mechanisms. Now try without transport layer security:
telnet <your server IP address> 143
01 LOGIN user password
That should be forbidden because of LOGINDISABLED.
