[Pkg-exim4-users] exim4 with smtp authentication

[Thijs Koetsier | Exception]

Hi Christoph,

You'll have to specify who you would relay for and who not.

In my configuration I use a textfile in /etc/mail/exim4/relay_hosts
In that file are hosts (IP addresses) of machines who are allowed to send
mail using my smtp-server.

The configuration in my main/01_exim4-config_listmacrosdefs is:

hostlist relay_from_hosts = /etc/mail/exim4/relay_hosts

an example of that file is:

# localhost
127.0.0.1
# my machine at work
xxx.123.456.789
...etc...

If this is done (and as Marc pointed out; do it quick or we'll all be
recieving unwanted mail from your server till you're blacklisted and all
your work has been useless), you could also set up individual users from
other than the specified (IP#) locations to use your server for sending
mail.
This is done by SMTP-authenticating. In your
/usr/share/doc/exim4/README.SMTP-AUTH you can - for starters - read how this
works. 

Cheers,
Thijs
