My notebook PC is "falkor". When I am in my office, it becomes "falkor.off.the-strategis.com. When I am at home, it becomes "falkor.home.the-strategis.com". Neither "off" nor "home" is really out there in the public DNS as an officially delegated zone. Apart from showing up in obscure Email headers, they should be pretty much invisible to the Internet. > datapotata.off.the-strategis.com. That is the internal name of the mail server that sits at my office. > I just tried a host name lookup for > your server and couldn't find an ip address for it. It is reached for incoming SMTP Email by the name "lab.the-strategis.com", which resolves to 209.242.32.238. > However, the redhat server thinks it's 209.242.32.237??? > I couldn't do a reverse lookup on that either? The ISP from whom we get our T-1 connection has the Cisco set up to map any outgoing connections from our office out as coming from the .237 address, rather than the .238 address. I don't understand why, but they seem to like it that way. I'm not sure whether it is appropriate to give that address a reverse lookup name, since no forward connection to it would go anywhere useful. > BTW, notice that you authenticated to your server. Yup. When I sit with "falkor" in my office, it works fine. When I sit with "falkor" at home, it works fine. When I sit with "falkor" at my client's site, it pretends it does not know me. Same systems. Same mail software. Same config. I'm racking my brain, trying to figure out what the difference might be that is causing this. (And, simultaneously trying to find time to get "better" authentication configured.) One thing I just thought of. Sitting here at my client's site, "falkor" is just plain "falkor", because there is no Primary DNS Suffix defined. I don't see why that would confuse Sendmail into ignoring my login/password authentication, though. Thanks!
