My server is not under high load, and qmail sure seems to work correctly. Googling, the only plausible bug report I could find was that some OS'es interpret the IP address 0.0.0.0 to mean the local machine, and some disallow it as an illegal IP address. It seems that qmail's intention is that 0.0.0.0 is illegal (as it is on OpenBSD(?)) If that is not also the case for FreeBSD, that might mean a qmail binary distribution is out of the question (based on Dan's statement "If there's something about a system (compiler, libraries, kernel, hardware, whatever) that changes qmail's behavior, then that platform is /not/ supported, and you are /not/ permitted to distribute binaries.") -Chris
