Re: [dspam-users] Re: qmail appliance

"bounce before accepting", I meant deny. You can also
qmail deliver to postoffice software, and deny 5.5.1 if
fail.

# .qmail
# | [try delivering to postoffice software like vpopmail]
| echo "Sorry, no mailbox here by that name (#5.1.1)" ; exit 100

That's not safe or rfc-non-ignorant unless for every
virtual domain you have

# virtualdomains
postmaster@domain.tld:someuser@deliverable.tld
abuse@domain.tld:someuser@deliverable.tld

#and perhaps

root:someuser@deliverable.tld
root@domain.tld:someuser@deliverable.tld
mailer-daemon@domain.tld:someuser@deliverable.tld

and I was probably wrong about control/locals accepting
usernames but it doesn't matter, if you do have
deliverable aliases for postmaster@ and abuse@ and
then have .qmail set to deny all non-deliverables, then
you have the same as any "modern" mta, a directory
of users(qmail deliverable maildirs make a de facto
directory), and deny others rather than double-
bouncing all of them.
