With address_verify_*_*_time im not understanding the difference in
behavior between refresh and expire. The manual says:
"parameters that control how long address verification results are
cached before they need to be refreshed, and how long results can remain
unrefreshed before they expire"
If the refresh time is 3h doesn't that mean the answer is cached for 3
hours and after 3 hours (upon receiving mail) postfix will attempt to
verify the address again? How is that different than the answer
expiring? Can you explain the mechanics of what postfix is doing with
refresh vs expire?
