=head1 NAME
|
|
|
|
buildvirtuser - Build virtusertable support from a directory of files
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
buildvirtuser [-f] [-t]
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
buildvirtuser will build /etc/mail/virtusertable.db and /etc/mail/virthosts
|
|
based on the contents of the directory /etc/mail/virtusers/. That
|
|
directory should contain one file per virtual domain with the filename
|
|
matching the virtual domain name and the contents containing a list of
|
|
usernames on the left and the actual address for that username on the
|
|
right. An empty left column translates to the default for that domain.
|
|
Blank lines and lines beginning with '#' are ignored. Occurrences of
|
|
$DOMAIN in the file are replaced by the current domain being processed.
|
|
Occurrences of $LHS in the right hand side are replaced by the address on
|
|
the left hand side.
|
|
|
|
The -f option forces the database to be rebuilt regardless of whether
|
|
any file changes were detected.
|
|
|
|
The -t option instructs the program to build a text file instead of a
|
|
database. The text file can then be used with makemap.
|
|
|
|
=head1 CONFIGURATION
|
|
|
|
In order to function properly, sendmail must be configured to use these
|
|
files with:
|
|
|
|
FEATURE(`virtusertable')dnl
|
|
VIRTUSER_DOMAIN_FILE(`/etc/mail/virthosts')dnl
|
|
|
|
If a new domain is added (i.e., by adding a new file to
|
|
/etc/mail/virtusers/), the sendmail daemon must be restarted for the change
|
|
to take affect.
|
|
|
|
=head1 EXAMPLES
|
|
|
|
Here are some example files from the /etc/mail/virtusers/ directory:
