given than

accept conditionA
        endpass
        conditionB

is equivalent to:

deny conditionA
      !conditionB

accept conditionA
        conditionB

in either order

and that you would need

conditionB =
           verify = recipient
           insert into db

but that when verify is false there is no need to do the lookup to
establish if conditionB is false, and it is exactly when verify is
false that you would need to insert in the database

I would say that you cannot do this with the accept...endpass alone.

Instead I would split this as depicted above:

deny domains = +local_domains
      !verify = recipient
      insert into db

accept domains = +local_domains
      verify = recipient

in the order that you find more convenient (that is, iff you reject
more than accept put the deny before)

or equivalently, but more cleanly, precede the accept...endpass with

warn domains = +local_domains
      !verify = recipient
      insert into db
