+Wildcard DNS is supported for hosteddomains by placing a single period
+character before the domain name. For example, the hosted domain entry
+".domain.com" will cause Courier to accept mail for "anything.domain.com".
+.PP
+Courier will accept mail for <address@any.thing.domain.com> and attempt
+to deliver it to the local mailbox <address@any.thing.domain.com>, 
+and if that fails then attempt to deliver the mail to the local 
+mailbox <address@.thing.domain.com>, then finally <address@.domain.com>
+.PP
+NOTE that there is a period after the '@' character. If you want all mail 
+for any.thing.domain.com to be delivered as though it were sent to domain.com, 
+you should define an alias for the domain, for example:

+.nf
