IP-less Virtual Hosting module
==============================

	This module  implements virtual hosting, however,  it does not
	require an unique IP number. 

	This is accomplished  by using the Alias module  (or any other
	that provides the necessary hook). 

	When using this module,  the client should format the argument
	of the USER command as follows:

		joe.user@virtual.domain.org

	If  the client  does  not allow  the  at-mark (@),  it can  be
	replaced by the percent sign (%). So

		joe.user%virtual.domain.org

	Means exactly the same, but

		joe.user@another.domain.org

	May refer to another user.

	The  table used  to do  the  mapping is  like the  /etc/passwd
	file. The  first two columns are  used by the  Alias module to
	determine the real user-name, the third one is the path to the
	mailbox. 

	For example:

		joe.user@another.domain.org:boss:/var/mail/the_boss
		joe.user@customers.com:customer1:/var/mail/customers/1

	Means that if the client sends joe.user@another.domain.org, as
	the user-name, then  the daemon will determine that  it is the
	`boss' user,  and mail should be  read from /var/mail/the_boss
	file.  Also,  it specifies  that  if  the  client logs  in  as
	joe.user@customers.com, then it is the `customer1' user, whose
	mailbox resides in the /var/mail/customers/1 file.
