[Dovecot] protocol configure confusion

The docs say:

*protocol*s = imap *imaps* *Protocol*s we want to be serving: imap *imaps* pop3 pop3s If you only want to use dovecot-auth, you can set this to "none".

and.....

If you want to specify ports for each service, you will need to configure these settings inside the *protocol* imap/pop3 { ... } section, so you can specify different ports for IMAP/POP3. For example:

# *protocol* imap { # listen = *:10143 # ssl_listen = *:10943 # .. # }

So if I want to run both imap and imaps AND configure the port, do I do:

# *protocol* imap { # listen = *:143 # ssl_listen = *:10943 # }

OR

# *protocol* imap { # listen = *:143 # } # *protocol* imaps { # listen = *:993 # }
