Hi! As the title says, I'm stuck at administrator level test and I don't know what to do next.
I've got a windows computer with a fixed IPv6 address and set up Ability Mail Server 2012 on it. The server is set to prefer IPv6 over IPv4. I can send and receive mails fine using IPv4 (tested with Gmail) and I can telnet from the router into the server using its IPv6 address. The address pings fine from the Internet too. Unfortunately, I don't have a computer with IPv6 at another location, so I can't telnet into the server and test it that way, but I think that my firewall settings are fine. Right now, I've set it to accept traffic on all ports (yes, I know that's unsafe!). Also the Windows firewall is disabled.
So when I input the mail address on the web page and click on the send mail button, I get two rotating arrows which keep doing that until I refresh the page. Once I do that, I get the send mail button again. Is this normal behavior? On wireshark, don't see anything trying to make contact with the computer running the server, so I guess that I may have a problem somewhere in the DNS configuration.
I've been provided with domain rm1211.s.raf.edu.rs by my school for experimental purposes and I've set the MX record to point to mail.rm1211.raf.edu.rs. When I do nslookup of that, I get:
root@OpenWrt:/# nslookup mail.rm1211.s.raf.edu.rs
Server: 127.0.0.1
Address 1: 127.0.0.1 localhost.
Name: mail.rm1211.s.raf.edu.rs
Address 1: 2001:470:1f0b:de5::5 mail.rm1211.s.raf.edu.rs
Address 2: 77.105.40.140 77-105-40-140.adsl-2.sezampro.rs
The dig for MX record of my domain looks like this:
root@OpenWrt:/# dig mx rm1211.s.raf.edu.rs
; <<>> DiG 9.7.2-P3 <<>> mx rm1211.s.raf.edu.rs
;; global options: +cmd

Both outputs looks fine to me, so I'm out of ideas where to look for troubleshooting ideas.
What do I do now?
