Hmmmm, if you're right then that would be great. I assume that you can turn on this sort of reverse lookup if you want but I don't think it's on by default. [EMAIL PROTECTED] jeff]$ telnet localhost 25 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. 220 superman.ivb.sil.org ESMTP helo big_fat_ugly_spammer 250 superman.ivb.sil.org Ok. helo [EMAIL PROTECTED] 250 superman.ivb.sil.org Ok. quit 221 Bye. Connection closed by foreign host. [EMAIL PROTECTED] jeff]$ And since I have lots of local users connecting to this machine to send mail (using their machine name as the HELO) then I don't think I can turn this on so I've never looked into it. But "out of the box" I think that courier will accept mail for valid users from anywhere, which is why accepting mail for ANY user seems like a bad idea to me. But hey, as my wife can tell you, I'm wrong all the time, so let me know if I've misunderstood how all this works! :-) Jeff Jansen ------------------------------------------------------- This SF.net email is sponsored by: IBM Linux Tutorials.
