FEATURE(domainmap) Macro
                                       
   The existing virtusertable feature distributed with sendmail is a good
   basic approach to virtual hosting, but it is missing a few key
   features:

1. Ability to have a different map for each domain.
    2. Ability to perform virtual hosting for domains which are not in $=w.
    3. Ability to use a centralized network-accessible database (such as
       PH) which is keyed on username alone (as opposed to the
       fully-qualified email address).

The FEATURE(domainmap) macro neatly solves these problems.
   
   The basic syntax of the macro is:
        FEATURE(domainmap, `domain.com', `map definition ...')dnl

To illustrate how it works, here is an example:
        FEATURE(domainmap, `foo.com', `dbm -o /etc/mail/foo-users')dnl

In this example, mail sent to user@foo.com will be rewritten by the
   domainmap. The username will be looked up in the DBM map
   /etc/mail/foo-users, which looks like this:
        jsmith  johnsmith@mailbox.foo.com
        jdoe    janedoe@sandbox.bar.com

So mail sent to jsmith@foo.com will be relayed to
   johnsmith@mailbox.foo.com, and mail sent to jdoe@foo.com will be
   relayed to janedoe@sandbox.bar.com.
   
   The FEATURE(domainmap) Macro supports the user+detail syntax by
   stripping off the +detail portion before the domainmap lookup and
   tacking it back on to the result. Using the example above, mail sent
   to jsmith+sometext@foo.com will be rewritten as
   johnsmith+sometext@mailbox.foo.com.
   
   If one of the elements in the $=w class (i.e., "local" delivery hosts)
   is a domain specified in a FEATURE(domainmap) entry, you need to use
   the LOCAL_USER(username) macro to specify the list of users for whom
   domainmap lookups should not be done.

To use this macro, simply copy this file into the cf/feature directory
   in the sendmail source tree.  For more information, please see the
   following URL:

http://www-dev.cites.uiuc.edu/sendmail/domainmap/

Feedback is welcome.
