~control/rcpthosts.cdb

Default:

~control/rcpthosts and ~control/morercpthosts.cdb

Notes:

qmail-smtpd reads ~control/locals or ~control/locals.cdb as well and there is no need anymore to replicate all domains here too.
Only domains you are doing queueing for must be listed here.
As soon as you regenerate ~control/rcpthosts.cdb it will become active.
Use qmail-cdb to create the ~control/rcpthosts.cdb file.
Alternatively you can do "make" in ~control/ directory. See the Makefile for more information.
If this file exists ~contol/rcpthosts and ~control/morercpthosts.cdb are ignored.
