You would need to open all necessary ports for in and out. the commands
being sent to the server (inbound) come in on the same port the response
back to the client (outbound) travel on.
So for these services open both in and out:
SMTP 25
POP3 110
HTTP 80
SSL 443
you can look in your services file (using notepad) to see if there are
others you may want open.

I would only open up inbound ports 25 and 80. I don't believe that I-Mail
needs port 443 open. Then, if you wanted to secure it even more, only allow
port 110 for outbound traffic. I am not sure if you will need to open up
port 80 outbound as well.
Also, depending on what firewall software/ hardware you are using, you can
also block/ allow port access by IP addresses or IP address ranges to
further secure the server.

What is the best way to secure a server IF I want to allow access both by
web and Outlook/Outlook Expree or similar program?
