So noone can fake one of your domains and use your server as relay.

They WILL do so.

You don't have smtp-auth running if you don't lookup the data somewhere.
You just do a simple lookup for the data in your database.
Your server_condition should look like this one:
server_condition = ${lookup mysql {select 1 from passwd where \
user=$quote_mysql{$1} and passwd=${quote_mysql:$2}}{yes}{no}}
You need to adjust this a little bit for the different authenticators
(using $1 and $2 vs. $2 and $3). And maybe you need to use ${md5:} or
something else, if you store your passwords encrypted, it depends on your
setup.
If you want pop-before-smtp you need either a pop-daemon or a logwatching
utility, that writes the ip-address to some file, or creates single files
with the ip-addresses in a special directory.
Add something like this at a good place to your rcpt_acl,
accept hosts = dsearch;/var/run/popusers/
to search for /var/run/popusers/$sender_address
or
accept hosts = dbm;/etc/exim/popusers.dbm
to search a simple dbm-file where your daemon/logwatcher writes too
