Issue Qmail - CR (carriage return) and LF (line feed) problem

[Rendor9]

Hello! I have a problem with qmail, which is rejecting send emails from 2 email accounts in particular. When I enter through webmail everything works ok but when I use the blessed "MS Outlook" installed on PC's I get an error of the type: "51 See http://pobox.com/~djb/docs/smtplf.html" wich means "Bare LFs in SMTP" , which seems to be some CR (carriage return) and LF (line feed) problem. I have no idea if this can be fixed by configuring the outlook client or running some command in qmail.

I would greatly appreciate help. Thanks!!
