This comes into play if your client issues an SMTP AUTH command, which is a setting in most mail clients that looks like "this server requires me to authenicate." With people on the inside of your network usually the RELAYCLIENT="" is set in your smtpd/tcp file meaning that they can send mail to whomever without any checks. People outside of your network do not get this RELAYCLIENT setting and so they can only send email to domains listed in your rcpthosts and locals file. However if they ask to do an SMTP AUTH and they pass (ie username/password works) then they can send mail like they were on the inside of your network, with the RELAYCLIENT setting on. People use SMTP AUTH so that their people outside of the LAN can relay mail through the corporate mail server. Another solution to this is SMTP after POP, which the "pbs" functions can work with in qmailldap. So to answer your question: no, you do not HAVE to login to send mail, but it gives you the ability to let people outside of your network relay mail through you. Hope that helps, and my apologies if you already knew all this. Chris
