Secure SMTP Configuration

This page deals with outgoing mail only. If you are getting a "Relaying Denied" message, this is where you need to be. This page does not apply to Webmail or to receiving mail.

SMTP (Simple Mail Transfer Protocol) is the method your computer uses to communicate with one of the Citadel Network mail servers. There will be a separate section in your email software for configuring SMTP. Following are instructions for configuring SMTP on the most common email clients.

In the following instructions, replace johndoe with your email username (the part of the email address before the @), and mycompany.com with your email domain (the part of the email address after the @).

NOTE: If your email domain is franklin.cnz.com, fayette.cnz.com, or rush.cnz.com, use cnz.com for the SMTP domain.

Thunderbird is the recommended email client, and is available on our Downloads page.

Starting on the main Thunderbird menu, select Tools | Account Settings | Outgoing Server (SMTP) | Edit.

The Description is only for display purposes. It should be something like "Your Organization Mail Server".

Set the server name to smtp.mycompany.com.

Check Use name and password.

Set the User Name to your full email address.

Under Use secure connection, select TLS (the image below shows "TLS, If available", but TLS is now recommended).

Press OK to return to Account Settings, and OK to finish.

The first time you send mail, you will get the warning Website Certified by an Unknown Authority. Select Accept this certificate permanently and press OK.
