=head1 NAME
|
|
|
|
auth_vpopmail - Authenticate against libvpopmail.a
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
This plugin authenticates vpopmail users using p5-vpopmail.
|
|
Using CRAM-MD5 requires that vpopmail be built with the
|
|
'--enable-clear-passwd=y' option.
|
|
|
|
=head1 CONFIGURATION
|
|
|
|
This module will only work if qpsmtpd is running as the 'vpopmail' user.
|
|
|
|
CRAM-MD5 authentication will only work with p5-vpopmail 0.09 or higher.
|
|

|
|
|
|
Decide which authentication methods you are willing to support and uncomment
|
|
the lines in the register() sub. See the POD for Qspmtpd::Auth for more
|
|
details on the ramifications of supporting various authentication methods.
|
|
