What does this patch do that chkuser doesn't already do?
Validrcptto uses ONCHANGE to monitor actions that add or delete
accounts on the mail server. The valid address list is stored in
a .cdb file that is easy to copy to other servers in a cluster.
Earlier versions used cron to scan the user list periodically.
Chkuser links to vchkpw and valias_<some kind of get> to determine
if an address is valid. This should be much faster, but only works
on the local machine. Maybe there could be a version that works
with vpopmaild, but still I think validrcptto is a better choice
for clusters.
In the clusters I build, I always have NFS mounts of the mail spool
on the smtp boxes for just this reason. chkuser works fine if it has
access to local files, and there's no syncing needed.
