| 32 | =head1 NAME |
---|
| 33 | |
---|
| 34 | buildvirtuser - Build virtusertable support from a directory of files |
---|
| 35 | |
---|
| 36 | =head1 SYNOPSIS |
---|
| 37 | |
---|
| 38 | buildvirtuser [-f] [-t] |
---|
| 39 | |
---|
| 40 | =head1 DESCRIPTION |
---|
| 41 | |
---|
| 42 | buildvirtuser will build /etc/mail/virtusertable.db and /etc/mail/virthosts |
---|
| 43 | based on the contents of the directory /etc/mail/virtusers/. That |
---|
| 44 | directory should contain one file per virtual domain with the filename |
---|
| 45 | matching the virtual domain name and the contents containing a list of |
---|
| 46 | usernames on the left and the actual address for that username on the |
---|
| 47 | right. An empty left column translates to the default for that domain. |
---|
| 48 | Blank lines and lines beginning with '#' are ignored. Occurrences of |
---|
| 49 | $DOMAIN in the file are replaced by the current domain being processed. |
---|
| 50 | Occurrences of $LHS in the right hand side are replaced by the address on |
---|
| 51 | the left hand side. |
---|
| 52 | |
---|
| 53 | The -f option forces the database to be rebuilt regardless of whether |
---|
| 54 | any file changes were detected. |
---|
| 55 | |
---|
| 56 | The -t option instructs the program to build a text file instead of a |
---|
| 57 | database. The text file can then be used with makemap. |
---|
| 58 | |
---|
| 59 | =head1 CONFIGURATION |
---|
| 60 | |
---|
| 61 | In order to function properly, sendmail must be configured to use these |
---|
| 62 | files with: |
---|
| 63 | |
---|
| 64 | FEATURE(`virtusertable')dnl |
---|
| 65 | VIRTUSER_DOMAIN_FILE(`/etc/mail/virthosts')dnl |
---|
| 66 | |
---|
| 67 | If a new domain is added (i.e., by adding a new file to |
---|
| 68 | /etc/mail/virtusers/), the sendmail daemon must be restarted for the change |
---|
| 69 | to take affect. |
---|
| 70 | |
---|
| 71 | =head1 EXAMPLES |
---|
| 72 | |
---|
| 73 | Here are some example files from the /etc/mail/virtusers/ directory: |
