Windows 2008/Exchange Server 2010 Public Port Security
Hi Experts,
I have hosted Microsoft Exchange 2010 in a dedicated server hosted outside form our company network. I'm planning to allow only RDP, OutLookanyware (SSL), POP3 SMTP, and IMAP to all the user access.
So can I close all ports listed on the Inbound except above port I required ?
What are best practices for these sort of set up ?
Thanks !

That's right only open the ports you need. You might need port 80 also

Thanks for the comments, I have closed most of all inbound ports leaving only SSL, SMTP, POP, IMAP, RDP. Finally for some reason port 25 was not accessible after I blocked all the others.
How do I understand all these relevant ports only for operate the email server. Any helpful resources would be highly appreciated.

Do you mean to check the ports what you allowed is working or not ? If so then it can be done through telnet.
Note : You may need to add this telnet feature on your windows features
Example : on you command prompt type
telnet mail.yourdomain.com 25 (SMTP)
telnet mail.yourdomain.com 110 (POP3)
telnet mail.yourdomain.com 80 (HTTP)
