1. Your MX Record will will point to mail.yourdomain.com then an A Record
will need to be created to point to your mail.yourdomain.com with Static IP
you have been assigned. The Static IP in this case being 217.17.239.120.
Yes for opening port 25 and 110 on your router, you should also open port 80
and 443 for OWA & SSL.

FYI: Also have the ISP create a Reverse DNS Lookup Record for
mail.yourdomain.com.

2. That is correct unless you are using some type of firewall enabled with
Router which may require a rule for outbound SMTP and POP3.

3. Third Party will be needed for POP3 Connecter but my question is why?
SMTP provides so much more and if you are going through all this work to
setup your Exchange Server for SMTP, why? Exchange is built on SMTP and you
lose so much by stripping it down to just a POP3 server.

NOTE: Recommend you purchase or have good Antivirus and AntiSpam software
for your Exchange Server as this is critical in todays world. I like Trend
Micro Client/Server/Messaging Suite www.trendmicro.com or GFI Mail Security
at www.gfi.com
