have you created DNS records for each of those services pointing to the mail server?
Then you need to make sure that your firewall has rules specified to allow access through.
And then you need to make sure that the POP service is enabled and running as well as the IMAP service and SMTP....

Not sure what you mean by default POP3, SMTP and IMAP addresses, can you elaborate a little bit, do you mean the port numbers?
From the sounds of the question, what you are looking to change is the domain names, that is handle by DNS.  You need to create records in your DNS internal and external and point it to the IP address of you mail server.
If you are looking to connect your clients to your exchange server on the inside, they do not use pop / imap or smtp you would connect using mapi...though outlook settings select the exchange option, all you need is the exchanges servers machine name.
Preferred method for outside connections to your exchange server would be RPC over http, this will take some configuring of your exchange server.
