I have some user email addresses (in domains that are specified as

Do I still need to list them in virtual_alias_maps, or is
check_recipient_access processed first?
you can keep it in reject_unlisted_recipient.

Thanks, that was a useful pointer... :)
Further reading tells me that if reject_unlisted_recipient is not
specified in my smtpd_recipient_restrictions it is processed after the
restrictions listed.
So: an email to one of my users rejected with 550 by
check_recipient_access happens before reaching
reject_unlisted_recipient.
I believe I do *NOT* need to have the user listed in
virtual_alias_maps as a valid user, as the inbound email will never
reach the reject_unlisted_recipient check - correct?
that's what I was trying to say.
you'd need to explicitly list reject_unlisted_recipient before check_recipient_access
to have it different.
reject_unlisted_recipient is not needed unless you set
smtpd_reject_unlisted_recipient=no or you want to reject invalid users before
checking check_recipient_access
- you don't want zthis.
one of my friends stated that fake "user doesn't exist" rejections/bounces
helped him get rid of many spams years ago
- It won't be the case nowadays.
