thanks! but im still running into problems, i put the debug output here...

>> hostlist relay_from_hosts = 127.0.0.1
>it's an good idea to add your local ip's here too


ok, i did so...

i fixed that

done! i commented out the last sender verify, and put it on another
position if everything is well

thats right, maybe in the near future i will take a closer look at them

yes i realy need it, because local is a postgresql keyword i have to put
"" around it ;)

ok, i did so... but what if a sender fakes his ip as the spammers will do?

ok, i tried
    exim -d+dns -bt someaddress@???
, this is what the debug output says:

why does it match my local_domains list?

-->> yahoo.de in "@:pgsql;SELECT domain FROM domain WHERE aktiv=1 and
"local"=1"? yes (matched "pgsql;SELECT domain FROM domain WHERE aktiv=1
and "local"=1")

thanks for any suggestions...

Try again....

Nope, (at least not in most cases) if you are a backup mx for the
relay_to_domains the dnslookup router just tries to send the mail to the
primary mx. If you have a destination that is "behind you", and there is
no primary mx record that you could send the mail too, you need a
manualrouter, to say "hey, mails for this domain to this mx please".

add :0.0.0.0 here

mostly, yes
