The first rule of Exim Expansion Club is - check the braces
The second rule of Exim Expansion Club is - CHECK the braces

Right now, you compare the result to {${local_part} {yes}{no}}, and the
closing brace of ${if is missing.

Use {$local_part} {yes}{no}} and it should do what you want.
(btw, {no}{yes} if it's used in a deny stanza)


but considering the third rule (don't use ${if } if you don't have to),
you should check if you can simplify the condition, like:

${lookup mysql{SELECT...} {yes}{no}}

I.e., if the lookup succeeds, the condition is true.

(Or use the recipients condition, but that's a matter of taste.)

Actually, you _can_ use recipient verification. If you have a special
router for the hosts you relay for, move the condition there. Just make
sure no other router handles that mail (i.e. add "!+relay_domains" to the
domains condition of your dnslookup router)
