Don't we all love brain-dead systems. I recently added a translation mapping for SMTP server inputs. That was meant to map inputs from brain-dead SMTP clients into something that satisfies basic SMTP syntax rules. Perhaps I should also add a translation mapping for inputs from SMTP servers, so that in the future, one could replace the above reply by a 4xx class reply. Wietse
