It's all been extremely helpful and educational. There are A records for everything. For example gh-systems.com.zone names ns3.intelli-media.com as NS, and in intelli-media.com.zone there is an A record for ns3. Most of today was wasted away fighting with an Exchange 2000 server - still unresolved, so I didn't have much time to work on the DNS stuff. Interestingly the Exchange issues _might_ be DNS related and when looked at from the generic mail server point of view, sort of on-topic too. Messages local to the machine are moving, but _some_ to external domains have been sitting in the queues; something along the lines that the messages were rejected by the _receiving_ servers. An associate of mine suggested that mail servers are doing reverse lookups on my box, which are failing. (And would have had to have been put on a black-hole list for a bunch of them to do it at the same time.) In the mail header the sending server is imediaexch02.imedia.intelli-media.com, the MX record for intelli-media.com points to email.intelli-media.com, the A record of which is 146.145.39.195. A reverse lookup on 146.145.39.195 returns mail.mmp-inc.com (which is an entry left from a previous ATX's customer) which doesn't match. I called up ATX and asked them to change the reverse entry for 14.145.39.195 to imediaexch02.imedia.intelli-media.com, but the tech put in imediaexch02.imedia.intelimedia.com, one of our other domains mistakenly! This change has propagated somewhat over the 'net, but not fully yet. I requested another change to imediaexch02.imedia.intelli-media.com but see no hint of this yet. Found a cool site, <http://www.dnsstuff.com> in the process though. Even if a reverse lookup on 146.145.39.195 results in imediaexch02.imedia.intelli-media.com, you can't do a forward lookup on imediaexch02.imedia.intelli-media.com as the subdomain imedia's DNS is purposely behind a firewall. I'm thinking now that I have to (1) force the server to put email.intelli-media.com in the message headers, (2) leave email.intelli-media.com resolving to 146.145.39.195 as it is now, and (3) have the ISP set the reverse mapping on 146.145.39.195 to email.intelli-media.com (instead of imediaexch02.imedia.intelli-media.com). Back to the thread: As Tom said I am still trying to get it to work locally. Based on all your input I am thinking it's a permissions problem as I just chose to have BIND installed in the Red Hat OS installation, and then later, as root, ftp'ed all the named files in place. Part of the reason I did this (other parts being newbie ignorance) was that I hosed the some of the keys up with "rndc-confgen -a" along the way. Didn't know about the user "named" either. -- - Zake _________________________________________________________________________ Philadelphia Linux Users Group -- http://www.phillylinux.org Announcements - http://lists.netisland.net/mailman/listinfo/plug-announce General Discussion -- http://lists.netisland.net/mailman/listinfo/plug
