When this is expanded, it will result in this
domainlist local_domains = @:localhost:mydomain.com\nmydomain2.com
What you want is something like this
domainlist local_domains @:localhost:mysql;select 1 from local_domains \
where domain='${quote_mysql:$domain}'
This just queries the database for "Do we know about this domain?"

The lookup yields the results line per line, but exim wants them seperated
by a :
It's better to use the lookup; style, because it acts like a command,
expansions will be done BEFORE the list is checked, and IIRC they make the
list uncacheable. The lookup;-parts will be matched ONLY when reached in
the list (And the list stays cacheable IIRC).
Btw, you should extract such data that's used very often to some very fast
datastore (local dbm/cdb-file) because this is needed very often.
