thank you. seems to be that
if address_verify_negative_refresh_time = 30m, the next attempt to reach a
specific recipient that is negative in cache, will still get the "old"
answer from cache if it is not expired by
address_verify_negative_expire_time. that is default 3d.
so in my case, postfix

hi,
we have
address_verify_negative_refresh_time = 30m active
(root@mx2:/var/lib/postfix# postconf -n | grep verify
address_verify_negative_refresh_time = 30m)
but the verify behavior is strange.
