You have 3 PTR records set up currently:
10.100.177.205.hcjbc.org.	IN	PTR	bcldap.hcjbc.org

10.100.177.200.hcjbc.org. IN PTR bcmailbox.hcjbc.org

10.100.177.210.hcjbc.org. IN PTR bcmta.hcjbc.org


The problem with them is that every application when looking up a PTR record for aaa.bbb.ccc.ddd will query the DNS server for "ddd.ccc.bbb.aaa.in-addr.arpa." but the PTR records you have setup only provide information for 10.100.177.200.hcjbc, so these records will never be used and are pointless. You should create the zone in-addr.arpa. similar to what I posted so that you have valid PTR records as a mail server needs them, and most other applications expect it.

(Also if you actually test those queries you are missing the "." at the end so it really returns "bcmta.hcjbc.org.hcjbc.org.", but since it will never get queried it doesn't really matter :rolleyes:)
Another thing which I forgot to mention last time is that MX records are supposed to have the FQDN of the server, not it's IP address. This is why it is showing "10.100.177.200.hcjbc.org." as your mail server. You entered in 10.100.177.200, and bind properly saw there was no terminating "." on there so it added the origin of "hcjbc.org.".
Since you have it split up I believe the MX record should be pointing to the MTA, so
hcjbc.org.	380000	IN	MX	10 bcmta.hcjbc.org.

Ok, so I have my Forward zone, Reverse zone, and my mx records set to the domain and not the machine. I get answers for all the above requested commands, but when I set up the bcmailbox (store) I get the password not verified. What am I to do now? I see alot of posting on this subject about the name not being verified with dns, but I can ping all three ways.

On bcmailbox what is the output of these:

dig bcmailbox.hcjbc.org. A

dig -x 10.100.177.200

That "dig -x" causes it to do a reverse lookup of the IP address. The full query as you can see is the "200.177.100.10.in-addr.arpa. IN PTR", just like I mentioned earlier. Simply add the domain like I showed you and that query should return results.
What exactly did you mean by "when I set up the bcmailbox (store) I get the password not verified"? What is giving you that error?

Hmmm, silly question: Are you sure that you actually added that zone to the zones BIND serves up? :rolleyes:

If it is showing up in the list of zones bind shows when it first starts, then I am not sure what the problem is here...


(Also just wondering: is bcdc behind a WAN link or something? "Query time: 716 msec" is retardedly long for a LAN connection)

Ah ha, there is your problem. The zone should be
zone "177.100.10.in-addr.arpa" {

The "0." that you had at the start would be an entry within the file (if it was a valid address to query).

So,.....Where do I send the check?......


It's the simple things in life that matter. Like not ending a statement with a semicolon. Or not escaping quotation marks correctly. Or adding an extra octet to your reverse zone.
