Setting

Description

Local Domain Name

The domain name of the server that MailEnable is installed on, or the default domain for the configuration. It is used for system messages, to announce the server when it connects to remote server, and when remote servers connect to MailEnable if the host name has not been specified.

Default mail domain name

The default mail domain name for the server, which usually matches the default MX record. For example, if you have configured mail.example.com in your DNS to point to your mail server, then you would enter this here. If a host name has been specified for an IP address on the server, then that value will override this host name.

DNS Address

The DNS that the local machine uses. If using more than one DNS, separate the addresses with a space character. If the SMTP service fails to connect to the first DNS, it will try the second or subsequent DNS. Use the DNS that is configured for the local network.

Specify the email address when sending notifications

The address from which notifications are sent. When MailEnable sends out email such as message delivery delays, or delivery failures, it will use this address as the "from" email address. Usually this would be postmaster@example.com, where example.com is your local domain name. Make sure this is a valid email address.

Enable NTLMv1 Authentication

If this feature is enabled then secure authentication between the server and the supported client is enabled.  This will allow the server to accept requests from the client to use secure transmissions for the authentication method.  The client also has to be enabled to use this secure authentication.  For example, in Microsoft Outlook the feature is called SPA – Secure Password Authentication. You should not enable this unless you have a specific reason, due to it being an old authentication method that is insecure and is being phased out by Microsoft.

Enable CRAM-MD5 Authentication

CRAM-MD5 Challenge-Response Authentication Mechanism is intended to provide an authentication extension that neither transfers passwords in clear text nor requires significant security infrastructure in order to function. Only a hash value of the shared password is ever sent over the network, thus precluding plaintext transmission. While slightly more secure than plain text, it is still recommended to always authenticate over a secure connection.
