DNS on Aruba PEC Non-authoritative

We have a PEC mailbox on a third level domain

@ posta.xxxx.it

We added the MX record with mx.pec.aruba.it

Someone has already happened with ARUBA Italy

the provider tells me that the setting is Authoritative on the third level domain.
But :

nslookup

set q=mx

pec.master-technology.it kehlani.ns.cloudflare.com

Server: 192.168.125.1

Address: 192.168.125.1#53

Non-authoritative answer:

pec.master-technology.it mail exchanger = 10 mx.pec.aruba.it.

Authoritative answers can be found from:

master-technology.it nameserver = kehlani.ns.cloudflare.com.

master-technology.it nameserver = reese.ns.cloudflare.com.

kehlani.ns.cloudflare.com internet address = 108.162.194.223

kehlani.ns.cloudflare.com internet address = 162.159.38.223

kehlani.ns.cloudflare.com internet address = 172.64.34.223

Here’s what a DNS lookup looks like right now:

$ dig @kehlani.ns.cloudflare.com pec.master-technology.it mx
...
;; QUESTION SECTION:
;pec.master-technology.it.	IN	MX

;; ANSWER SECTION:
pec.master-technology.it. 3600	IN	MX	10 mx.pec.aruba.it.

If you want to receive emails at [email protected], that configuration seems fine.

What problem are you experiencing more specifically?

I’m having trouble viewing emails from the provider and they tell me it’s Cloudflare’s fault:

"You need to contact Cloudflare and have the dns zone of the third level configured appropriately pec.master-technology.it

it is precisely the Name Servers set as authoritative on the second level domain that do not resolve the MX record of pec.master-technology.it:

C: > nslookup

Not sure what’s happening with your (or maybe their?) queries here. Are you on some corporate network? It looks fine for me from the “outside world” though so I wouldn’t worry too much about the MX record at this point. If you want to receive emails with the address format I mentioned in my first reply, then the MX part looks alright to me.

What does this mean more specifically? The MX record controls where incoming emails should be directed. If you are having issues with checking your email in an email client or through webmail, that is a different issue.

also to me everything is OK to how MX, the only thing that did not convince me, was that the ISP of the mail Server PEC, they say that “Cloudflare is wrong for them to manage MX set as authoritative”

My problem is that neither from Outlook (imap) nor from their web mail I can not receive or send mail. I think it’s an ISP problem

I am in a company network but we do not have the PEC server in house, the PEC mail is managed by an external server (ARUBA ITALIA), in Italy this certified PEC mail is used. That only we Italians have :frowning: ahhahaha

Oh, I see. If you can get into the webmail but not send and receive anything, the only thing I can come up with that might be related to Cloudflare is the Proxy status.

This is only applicable if you have set up a custom domain under master-technology.it for webmail access. In that case you might want to make the record “grey-clouded” (Proxy status: DNS only) if it isn’t already. In this scenario, requests will go straight to the webmail server without passing through Cloudflare (except for the DNS lookup). It ensures that Cloudflare features doesn’t interfere with the webmail application.

If you’re accessing webmail through another domain (not your own), I’m afraid it will be harder to assist you here.

Certified email… Today I learned something new :smiley:

and all in gray cloud, only DNS, with Proxy it could not work.

Right, thanks for confirming! Sorry, I’m out of ideas at this point, though. Maybe someone else has some input, but it seems like there aren’t much Cloudflare specific things to troubleshoot here :slightly_frowning_face:

Thanks to you ,
