Hmm. What if you get the latest version and just reverse this one change? I won’t see any obvious reason why it would change this, but I guess it could be possible in less obvious ways. Is this reproduceable, i.e. are all of these Postfix checks always failing or just rarely or most of the time or ..? And was this only with the Postfix user existence check or were LMTP deliveries in general failing?
