+DOTTED_USER(name)
+ Sometimes it is convenient to merge configuration on a
+ centralized mail machine, for example, to forward all
+ root mail to a mail server. In this case it might be
+ useful to be able to treat the root addresses as a class
+ of addresses with subtle differences. You can do this
+ using dotted users. For example, a client might include
+ the alias:
+
+ root: root.client1@server
+
+ On the server, the mail configuration would include:
+
+ DOTTED_USER(root)
+
+ Aliases on the server that would match this address would
+ be "root.client", "root.*", and "root", tried in that
+ order. You can specify multiple addresses either by
+ joining them in one DOTTTED_USER macro or by having
+ multiple macros:
+
+ DOTTED_USER(root)
+ DOTTED_USER(postmaster mailer-daemon)
+
+ defines three dotted users.
