=head1 NAME
|
|
|
|
auth_cvm_unix_local - SMTP AUTH LOGIN module using
|
|
Bruce Guenther's Credential Validation Module (CVM)
|
|
http://untroubled.org/cvm/
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
In config/plugins:
|
|
|
|
auth/auth_cvm_unix_local \
|
|
cvm_socket /var/lib/cvm/cvm-unix-local.socket \
|
|
enable_smtp no \
|
|
enable_ssmtp yes
|
|
|
|
=head1 BUGS
|
|
|
|
- Should probably handle auth-cram-md5 as well. However, this requires
|
|
access to the plain text password. We could store a separate database
|
|
of passwords purely for SMTP AUTH, for example as an optional
|
|
SMTPAuthPassword property of an account in the esmith::AccountsDB;
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
This plugin implements an authentication plugin using Bruce Guenther's
|
|
Credential Validation Module (http://untroubled.org/cvm).
