You're correct that the rcpthosts file would be a linear scan, but
qmail-smtpd also supports morercpthosts, converted to a cdb file
via the qmail-newmrh command.  The manpage for qmail-smtpd offers:

    Put your 50 most commonly used domains into rcpthosts, and the
    rest into morercpthosts

Is there a part of your problem not satisfied via use of the
morercpthosts and the qmail-newmrh command?
