I have a similar question regarding the error "550 Administrative
prohibition". I've been playing with cyrus <> exim and callout
verification.
Using Andrews great ACL's I am able to get a proper "5.5.2. Over Quota"
error message. But after a couple of 'tests' the
"verify=recipient/callout=random,5s" part of the acl gets a different
result.
Due to the call-out cache exim now determines (??) that the "Over Quota"
is a delivery error to the mailbox and gives a "550 Administrative
prohibition" in stead of the expected "Over Quota" status message.
Is this something we should learn to live with ?... Or should the error
message also be cached in the callout cache or something ?
( changing the "recipient/callout=random" -> "recipient/callout=no_cache"
fixes the problem, but caching would be nice ... )
