Administrator test: No MX found for your domain. Failed to get AAAA

[gviarengo]

Hi,
I suppose that now my mx record and aaaa record are fine:


viare-admin@viareadmin-D1826-G:~$ dig @ns2.he.net mx myviare.info +short
10 mail.myviare.info.
viare-admin@viareadmin-D1826-G:~$ dig @ns2.he.net aaaa mail.myviare.info +short
2001:470:1f13:1143::201
viare-admin@viareadmin-D1826-G:~$ dig @ns2.he.net -x 2001:470:1f13:1143::201 +short
mail.myviare.info.

Looks like you have a firewall blocking the packets. Notice how a traceroute to port 25 is rejected one hop before packets to port 80.

Obviously in this moment port 25 is blocked by firewall.
I open port only to do the test.

In any case the error message does not mean the port is blocked:

error I get is: No MX found for your domain. Failed to get AAAA

It's Like my mx record is not not correct or aaaa record but it seems correct:

viare-admin@viareadmin-D1826-G:~$ dig @ns2.he.net mx myviare.info +short
10 mail.myviare.info.
viare-admin@viareadmin-D1826-G:~$ dig @ns2.he.net aaaa mail.myviare.info +short
2001:470:1f13:1143::201
viare-admin@viareadmin-D1826-G:~$ dig @ns2.he.net -x 2001:470:1f13:1143::201 +short
mail.myviare.info.

I can see on forum that I' m not the one that got this issue.

Many replay point to wait for a flush of DNS cache server .....

Can it be the problem ?

I do not exclude any other problem on mail server .... but message refer to a dns problem on mx record.

If so how long I need to wait?

resolved .....
wait ... wait and wait and test passed
