How to configure and force users to use IMAP?

I have installed mail server with postfix and dovecot.
My clients use The Bat email client software.
While sending mails, they use tcp port 587 with STARTTLS.
And I disabled tcp port 25 for sending mails in firewall (in server).
Now, they receive mails via tcp port 110 POP3 protocol.
I want to use IMAP or IMAPS for receiving mails for my clients.
And I totally want to disable POP3 protocol.
1) I tried to change port number to 143 for receiving mails in "The Bat", but it cannot receive mails. How can I do it right?
2) Should I reconfigure dovecot for using IMAP/S only?
3) Is my idea is right?
PS: I opened port 143 on my server in firewall.

There wasn't told about IMAP/IMAPS and switching from POP3 to IMAP

Well... it should work like a charm with proper configuration. So you must have a misconfiguration between postfix and dovecot.

Make sure your dovecot configuration is done right.
(how to)
Depending on a version check if you have imap protocol enabled in:
/etc/dovecot.conf
/etc/dovecot/dovecot.conf
OR
/etc/dovecot/conf.d/10-master.confThan check if dovecot is listening on 143
Than check it from outside, that the port is really opened.
- Setup the client (how to)
EDIT: Issue was solved, problem was on clients side (Bat email client)
