Catch all seems broken?

[indreias]

by the way, the same problem was found on this thread:

Does catch-all work properly?

We have configured a mail domain with catch-all disabled (to reject mails to unknown user accounts). However, the domain does not report any rejection to the sending relay server and instead we can see this this mail in the Axigen queue with the remark “send failure”. This is not the expected behaviour. Why does this happen ? Thanks.

where it was explained that when a domain is in migration (intentionally or by mistake) the catch-all feature is not producing the expected results.

HTH,
