I can see the problem now, thanks for the clarification.
What I did was setting a flag if a 4xx code was received, not deleting
the entry from the retry-database if this flag is set. Further retries
will be delayed on transient failures, however the entry in the
retry-database would be deleted on a successful delivery to the host.
Not very elegant, ie quota-failures to recipients on the same host will
delay other messages until the next queuerun allowed by the retry-database.

Like «putting it onto the Wishlist»?
Urk, did I mention that 422 replies are also received on full disk?

Yeah! But you certainly will be able to make it!

PS: I cant remember passing this to any sendmail-list.
Was that another bug in sendmail?
