The Gateway Editor is reached by clicking the Gateways » New Gateway... or Gateways » Edit Gateway... menu selection on MDaemon's menu bar. It includes the following screens:
Use this dialog to designate the domain name for which MDaemon will be acting as a backup server or gateway. This is also where you will designate the folder used for storing the domain's messages.
If the remote domains server is configured to keep an LDAP or Active Directory server up to date with all of its mailboxes, aliases, and mailing lists, or if it runs a Minger server to provide remote address verification, you can use this dialog to specify that server and thus verify the validity of recipient addresses of incoming messages. When a recipient address is found to be invalid the message will be rejected. With this method you can avoid having to assume that all recipients of a domains messages are valid.
With this dialog you can declare a host or address to which the domain's mail will be forwarded as soon as it arrives. There are also options for stating whether a copy of these messages should be kept locally and for designating the port on which the forwarded messages should be sent.
Using the options on this dialog, you can configure MDaemon to respond to ETRN and ATRN requests made on behalf of the domain in order to dequeue its messages. You can also configure several other dequeuing related options.
Here you can create a POP3 or IMAP user account that will have access to this domain's stored mail. Using the name and password that are assigned here, a mail user agent (MUA) such as an ordinary email client or another MDaemon server can access the domain's mailbox and collect its mail.
This dialog is used for assigning a limit to the amount of disk space that the domain may use and the maximum number of messages that may be stored.
This screen contains a number of other options that will apply to the selected domain gateway. For example, you can enable/disable AntiVirus and AntiSpam scanning for the gateway, designate whether or not authentication is required when dequeuing mail, designate an authentication password, designate IP address connection restrictions, and several other options.
