I've been getting the dreaded 556 error occasionally for an address on our server (sa...@justcroft.com), and I can't quite diagnose the problem.
The address points to a couriermlm list, and normally goes fine, then every so often the BSS kicks in and customers complain they can't reach the address - it is the main point of contact for most of our customers, so pretty critical for our business. The problem is, I can't see any evidence of an error delivering to that address which might be sparking off the BSS. Given that it's a list, would a failed delivery to one of the list addresses do that? To try and work around the problem and ensure that delivery still happens, I have set opt BOFHSUPPRESSBACKSCATTER=none in bofh, although I stil have ESMTP_BLOCKBACKSCATTER=smtp/dsn in courierd - is that 'safe' (i.e. it won't get my server blacklisted...) ? And will it switch off the 556 messages? That's how I read the manual, but I might be wrong...
