Translations:Complete Virtual Mail Server/SMTP Authentication/6/en

Ideally the last option would be the used solution, as one authentication back-end would be used, courier-authlib. The cyrus-sasl plugin to talk to courier-authlib however will only work via a unix socket and thus if courier-authlib is not running on the same host as cyrus-sasl this would not work. The first approach should thus only be used if courier-authlib can not be used.
