Thx johnpoz!!! ATT was blocking port 25. I resolved the issues per your email below and then tried but still no luck. Checking my system to see if there are any configuration issues that I need to resolve.

johnpoz

what did you fix??  You still have the same problem

dig 5103.jasc22.com AAAA +trace

Notice when ns71.domaincontrol.com gets asked for AAAA of your mail host you get just SOA - fail!!

If one of the he.net servers get ask you return

5103.jasc22.com.        300     IN      AAAA    2001:470:d:ee7::2
;; Received 61 bytes from 2001:470:300::2#53(ns3.he.net) in 90 ms

But I still show that not answering on 25 anyway!!

telnet 5103.jasc22.com 25
Trying 2001:470:d:ee7::2...

Just hangs -- so you still have a dns problem, and you still have a port blocked problem.  So yeah email never going to work.

hi johnpoz.....so when i try to run dig 5103.jasc22.com AAAA +trace i get the following error. I ran other dig commands and it seems like it's working. Please let me know your thoughts. As well, I have included my mail.log and I received the email but still having issues with postfix.


s733l@5103:~$ dig 5103.jasc22.com AAAA +trace

; <<>> DiG 9.7.1-P2 <<>> 5103.jasc22.com AAAA +trace

However, when I run the following I get the results below.

johnpoz

I don't know how to say this any different..

Notice in your trace you hot that record from he.net server

5103.jasc22.com.   300   IN   AAAA   2001:470:d:ee7::2
Received 61 bytes from 2001:470:300::2#53(ns3.he.net) in 34 ms

But if you ask

asc22.com.      172800   IN   NS   ns71.domaincontrol.com.
jasc22.com.      172800   IN   NS   ns72.domaincontrol.com.

You do NOT get a AAAA response -- all server listed as your NS should have ALL records, you really should pull the domaincontrol.com servers out if they are not going to have all the records in them.

Im not currently at a location where I can connect via IPv6 would have to vpn into my home network or wait til get home.. But the box last couple times I have checked was NOT listening on 25 on that address

Still not showing your server listening on 25 on ipv6, did you turn it off already?

So I can telnet to the he.net mx server on ipv6

telnet 2001:470:0:76::2 25
Trying 2001:470:0:76::2...
Connected to 2001:470:0:76::2.
Escape character is '^]'.

But yours just sits there and port shows close on a port scan
Yours fails

Hey johnpoz, thx for checking! I got to Sage yesterday and the Administrator was the only test holding me up. The reason why you were unable to telnet was because l shutdown my machine. Great learning experience and appreciate your help!! ;D
