Tárgy: Re: [Exim] need help with smtp-auth and relaying
thanks nico,
thats a great help. i carefully read it and tryied around with a new
configuration.

now, i put the ACL's in the suggested order and changed my domain lists
to the following:

domainlist local domains =@ : pgsql;SELECT domain from domain where
aktiv=1 and "local"=1
and
domainlist relay_to_domains = pgsql;SELECT domain from domain where
aktiv=1 and "local"=0

and i set my relay from hosts list to:
hostlist relay_from_hosts = 127.0.0.1

so, i understand my mistake with the lookup in the domainlists and also
the acl stuff makes sense (i dont understand it well, but it may work *g*)

now i can send messages from yahoo or somewhere else to one of my
accounts on the server, and also send messages from an authenticated
host to my server.
authentication seems to work well,
but if i send a mail through my server to another doman which is not on
my server, i got an 'unrouteable address' -error?

what am i doing wrong?
any suggestions? i took my old config to send this mail to the list ;)

i put my new config on this place:
http://www.multiartstudio.com/Files/exim/exim2.conf.txt

another question:

does it make sense to set
domains = !+local_domains : !+relay_to_domains
in the dnslookup-router??

dnslookup:
driver = dnslookup
domains = ! +local_domains
transport = remote_smtp
ignore_target_hosts = 127.0.0.0/8
no_more
##############

you mean i results in something like 'true' and 'false'?


thanks in advance
