The Default Domain & Servers section can be reached via the Setup » Default Domain/Servers... menu selection and is used to configure your default domain and other server options. Only one default domain can be configured, but MDaemon can manage mail for any number of Extra Domains (MDaemon PRO only), and store mail for any number of Domain Gateways as well.
The Default Domain section contains the following dialogs, which are necessary for configuring MDaemon.
This screen contains your default domain's name and IP address.
Here you will specify the degree to which you want MDaemon itself to handle delivery of mail versus relaying it to an ISP, gateway host, or other server for it to deliver the mail for you.
This screen is used for configuring a number of server and email protocol related options. For example, there are options for choosing whether or not MDaemon's SMTP server will honor VRFY, EXPN, APOP and CRAM-MD5, and more. You can also set a message size limit, limit the number of RCPT statements allowed during the SMTP session, and configure a number of other options.
This screen contains the ports that MDaemon will monitor and use for SMTP and POP email delivery. You can also designate the port on which MDaemon will listen for IMAP events, the UDP port used for querying DNS servers, and a number of other port settings. In most cases the default settings will not need to be changed. However, being able to change your port settings is useful when attempting to integrate MDaemon with various other components or servers that you may be using on your network.
This dialog is used for designating your primary and backup DNS server IP addresses. It also contains various options governing MDaemon's handling of MX records.
This area contains various time limits that MDaemon will observe while connecting to remote hosts, waiting for protocol dialogs, waiting for DNS server responses, and so on. In addition, this dialog contains the Maximum message hop count limit, which is used to help prevent messages from being caught in a delivery loop.
Here you will designate the maximum number of concurrent session threads that MDaemon will use for sending and receiving SMTP, POP, and IMAP mail. You will also designate the number of messages that MDaemon will attempt to send or receive at the same time. In addition you can set a limit on the number of outbound SMTP messages that will be spooled per session thread.
