Re: [suse-security] Directory listing....
... check the qmail.org website, read the whole chapter about relaying, read
the newbies guide, read lifewithqmail, learn about smtp and pop3. you should
at least know the basics about the protocols and programs involved. smtp has
no method of user authentification, so you need to add that, e.g. by using
smtp after pop: first the user authenticates by creating a pop3 session,
then he/she is allowed to send mails through your server. but this method
has to be supported by your mailclient.

... but if you don't absolutely need that (because you have customers with
dynamic IPs from various ISPs), you should only allow the use of your smtp
server to send out mails from your local network.

best regards
