Is it doing sender address validation in any way, eg is the address represented by "logcheck@server1.example.com" a valid address, and/or is server1 making that verification correctly?
There is sender address validation, and it is a little complex. But it's not the issue in this case as both email addresses will work when sending mail from server0 and neither works when sending from server1. Thanks for the suggestion, I'm really stuck here.
I normally use exim, and there is a command line option to simulate an SMTP conversation from a given IP address and it basically logs everything that happens, every rule it traverses, and why it accepted/rejected/deferred/etc at any given point, optionally doing callouts or not (as obviously they interact with the real world so may not be desirable). Does postfix have such a thing? James
