The SSL POP3/IMAP utlity of the @Mail WebAdmin allows you to configure your mailserver's settings for POP3 and IMAP access via SSL/TLS. This allows for more secure connections to your POP3 and IMAP servers that adhere to the settings you define.
In the SSL POP3/IMAP utility, you have the following options:
Enable SSL Support - This allows you to enable IMAP-SSL and POP3-SSL when @Mail is started up via init.d. This edits the imapd-ssl and pop3d-ssl files (located in /usr/local/atmail/mailserver/etc/) so that it toggles the SSL support on.
SSL Cache Support - This enables the support of SSL-caching, should the instance that multiple SSL connections on your server are used concurrently, arise. You can easily disable this feature, should you experience problems authenticating via IMAP-SSL/POP-SSL. This option assigns a value to the TLS_CACHEFILE variable, found in your imapd-ssl and pop3d-ssl files (located in /usr/local/atmail/mailserver/etc/).
SSL POP3/IMAP Address - This option enables you to define the IP of the server IMAP-SSL and POP3-SSL connections are made to. The default value of '0' will bind the service to all IP's available on the server.
POP3-SSL certificate - This option allows you to specify which secure certificate to use for POP3-SSL. By default, this is created manually - but you can optionally have it reference to your own certificate file. This modifies the TLS_CERTFILE variable in the file: /usr/local/atmail/mailserver/etc/pop3d-ssl.
IMAP-SSL certificate - This option allows you to specify which secure certificate to use for IMAP-SSL. By default, this is created manually - but you can optionally have it reference to your own certificate file. This modifies the TLS_CERTFILE variable in the file: /usr/local/atmail/mailserver/etc/imapd-ssl.
