MDaemon contains full support for multiple domains, administered using the Domain Manager. Here you can manager the domain names, IP addresses, account and message pruning settings, Webmail settings, and other domain-specific options for your domains.
MDaemon supports both single and multiple IP addresses, and IP addresses can be unique to individual domains or shared between them. Further, several key features such as Accounts, Mailing Lists, and some Security Settings are on a per domain basis. When you create an account, for example, you must specify the domain to which the new account belongs. The same goes for Mailing Lists. This also means that features such as the IP Screen and IP Shield are tied to domains individually.
Some features, such as Name Matching under DomainPOP, are tied exclusively to the Default Domain. The Default Domain is also the domain displayed by default in various options, such as when creating new accounts or mailing lists. Further, to support MDaemon's handling of system messages, the following default Aliases point several reserved mailbox names to MDaemon's default domain name rather than to its other domains:
MDaemon@$LOCALDOMAIN$ = MDaemon@<DefaultDomain>
listserv@$LOCALDOMAIN$ = MDaemon@<DefaultDomain>
listserver@$LOCALDOMAIN$ = MDaemon@<DefaultDomain>
list-serv@$LOCALDOMAIN$ = MDaemon@<DefaultDomain>
Finally, in order to support multiple domains, by default MDaemon requires users to use their full email address (e.g. "user01@example.com") as their login value rather than using just the mailbox portion of the address (i.e. "user01"). Some very old mail clients, however, do not support using '@' in the login field. Therefore to accommodate those clients you can specify an alternate character on the System screen under Preferences. Further, this value can be up to 10 characters long, making it possible to provide a string of characters to serve as the delimiter instead of only a single character such as '$'. For example, using '.at.' will allow you to make logon values of "user02.at.example.com". You can also disable the full email address requirement, allowing the use of only the mailbox portion of the address as the login value, but that is not recommended and can cause problems when you have more than one domain.
Adding or Editing Domains
To add a new domain, click New on the toolbar. To edit a domain, select the domain and click Edit, or double-click the domain. This opens the Domain Manager for configuring or editing the domain.
Filtering the Domain List
You can sort the domain list in ascending or descending order by clicking the "Domain" bar just above the list. If you have a very large number of domains, however, and wish to display a specific subset of them, or you wish to jump quickly to a specific one, click Filter on the toolbar and type the domain name or some text by which to filter the list, and click Apply. Optionally, before clicking Apply you can switch the filter criteria from match to do not match, if you wish to filter the list based on the results not matching the text you typed. You can use wildcard characters * and ? to make searching easier.
For example, if you wish to jump quickly to the domain example.net, you can simply type "example.net" and click Apply. Then only example.net would be displayed in the list. Typing "*.com" would display all domains ending with ".com". In the latter case, switching the filter criteria to "do not match" would cause only domains that do not contain ".com" to be displayed.
To cancel the Filter and go back to the default list, click Filter again and then Cancel.
