Secured Email: For Gencom purposes, secured email is a cryptology process using a registered secured certificate to verify and prove you are who you say you are when you send an email or someone goes to your web site. For example, when you order online, that vendor must have a secure certificated web site. Cryptographically secured certificates are used for incoming and outgoing mail.
A certificate is an "electronic passport" that establishes your online entity’s credentials when emailing or doing business on the Web. When an Internet user attempts to send confidential information to a Web server or email server, the user’s browser or email program accesses the server’s digital certificate and establishes a secure connection.
Outlook accounts must have security enabled for SSL and have the correct secure server ports entered. Since you have purchased email accounts from Gencom, the Gencom secure email servers are providing a general security certificate free of charge. The email server internally verifies who you are since you set up an email account and it has all your business verification data. That is the kind of secured email you need to use.
