Me again. After having a problem with trying to connect to a greylist-protected mailing list, I've been reading & re-reading the docs on address_verify_negative_expire_time and address_verify_negative_refresh_time. I know these are different - but I'm afraid the difference as described in the docs is too subtle for me.
Does "expire" mean it is removed from the cache, and "refresh" tests to see if it is still invalid - and such tests are repeated at "refresh" intervals until either a positive response is obtained or "expire" time is reached (and the inverse for the "positive" settings)? If this is the case, it might seem obvious to some - but I'd appreciate that little bit of explicit instruction. Of course if I'm totally wrong - go ahead and slap me with the correct info. -- Daniel
