Secure POP3 and SMTP using SSL
Posted on 2006-06-20
I have windows 2003 and MS Exchange 2003 in the organization i work for. Some of the users need to access their email from outside the office. So I'm planning to setup secure POP3 and SMTP using SSL certificate for this purpose.
When a user is outside the office, I want to him/her to be able to connect to the Exchange using POP3 (SSL) and when they want to send mail out, they will send to the office Exchange SMTP server securely using SSL as well.
So question are:
1. do I have to buy two SSL certificates for this purpose? because I want to secure both POP3 and SMTP.
2. How do I configure the Exchange 2003 server to allow both secure and non secure connection (POP3 and SMTP). Because for internal user, there is no need for them to connect securely. but for external user, they have to connect securely.
