That depends on what you think as "valid". It needs some serious tweaking to have exim issue the correct HELO if the machine has more than one IP address, and it is _very_ hard to correctly HELO when exim is behind a NATting router whose outside interface might have changing IP addresses. I suspect that there is mail server software out there that doesn't allow tweaking the HELO name at all. Greetings Marc -- -------------------------------------- !!
