=head1 NAME
|
|
|
|
auth_vpopmaild - Authenticate to vpopmaild
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Authenticates the user against against vpopmaild [1] daemon.
|
|
|
|
=head1 CONFIGURATION
|
|
|
|
Add a line to C<config/plugins> as follows:
|
|
|
|
auth_vpopmaild
|
|
|
|
By default, the plugin connects to localhot on port 89. If your vpopmaild
|
|
daemon is running on a different host or port, specify as follows:
|
|
|
|
auth_vpopmaild host [host] port [port]
|
|
|
|
=head1 SEE ALSO
