[Pkg-exim4-users] exim4 with smtp authentication

[exim4 at wlassak.net]

Hello everyone,

i have a problem with my smtp server which runs on a Debian Sarge 3.1 Linux
System.

Relaying, ... works fine, but i like to have a smpt authentication for outgoing
e-mails. So far it is working.

To secure my server a bit, i want to deny unauthenticated clients to send mail.
For now they can do this, even if they are not in my local net.
I am allowed to send mails with and without authentification.

Do you know how to prevent this?

... Yes, I read the manual ...

Thanks for your help.

Regards
Christoph
