I have qmail + vpopmail 5.0 final release and my acount and other accounts that are on a lan and check every 2 minutes, gets password failed in the logs, but not in the email client; the email client (outlook,kmail, pine) checks perfectly. So my answer is... why ive get password failed in the log, when theres no problem in the client side (no boxes with the password failed warning etc). This no affect the dial up users, i dont have logs of it, and the two accoutns that are logged with password failed are in differents lans.
Sorry for my very poor english... Alejandro
