Changing Your Mail Server Settings

The control panel provides default configuration settings for the email server. You can change these settings to suit the needs of outgoing and incoming mail on your domain.

To change your email settings:

1. In the shortcuts section of the Home page, click Configuration (Email section).
   

   To get to the Home page, click Home on the navigation bar at left.

2. In the Configuration form, click Edit. The Edit Configuration form opens showing the current SMTP email settings.
3. In the Maximum Message Size field, enter the maximum number of bytes an email message can contain.

   Note: If you do not want to impose a limit on the message size, leave this field blank.

4. In the Relay Domains field, enter the names or IP addresses of the domains that can use this server as their SMTP mail server.
5. Depending on whether or not you want the control panel server to authenticate the email source before enabling further relay, select the appropriate Relay Status check box.
6. Click Update.  

Note that you cannot change SSL certificates for e-mail IMAP/POP3 services from the control panel.

To update an SSL certificates manually, run the following commands in the system shell:

$ cd /etc/pki/tls/certs
$ mv imapd.pem imapd.pem.bak

$ mv ipop3d.pem ipop3d.pem.bak

$ make imapd.pem

$ make ipop3d.pem

$ /sbin/service xinetd reload

Important: These SSL certificates are used for all customers' domains on the server. Individual SSL certificates per domain are not supported.
