Postmaster problem

Hello,
My domain name: mailsuit.com

I think I have configured all the records correctly. It looks correct in places like mail tester, mxtoolbox. Only postmaster is wrong. Postmaster has not fixed it for 20 days. That’s why my emails are going to spam in Gmail. I wonder if I have a mistake somewhere… Can someone check? Can you give me some advice?

Regards

Hello,

Could you please send a message to axigen[dot]team[at]gmail[dot]com so we could evaluate all headers and the different authentication results (for SPF, for DKIM, etc)?

HTH,

Hello Indreias,

I sent 2 mail…
1- from base domain name
2- from customer domain name

What is your idea?

Regards

Hello,

Both messages looks fine from all layers: SPF, DKIM and DMARC.

and these are the first checks to be done before going further.

Two things I’ve noticed:
1/ the IPv6 used to send the message from your client’d domain does not have a PTR record (it should match the EHLO string similar with IPv4) - not necessarily a very bad thing but something that you may try to fix (if possible).

2/ Both of your messages are detected by your own AS/AV filter as Spam (check X-AXIGEN-BD-Result message header) - and this is very strange…

Now, what I suspect about message delivery into the Spam folder is that the IP(s) used for the main domain and the hosted ones need to be “warmed” up (as explained here and here).

Also, the usual recommendation is to reply back to (some) of sent messages: like pressing “this is not spam” (if delivered into spam) and replying back. Also sending from them to your domain(s) and replying back.

Beside this, you may check the domain reputation with various on-line services like Spamhaus.

Another good idea is to use Gmail’s Postmaster Tools (where you could add your main domain and other ones as well) for any hints about why the messages are delivered into Gmail’s spam folder.

The last recommendation I have is to monitor your egress IP address into a DNSBL monitoring service (like HetrixTools) so you will know and be alerted asap about new listsings of your sending IP addresses into such databases.

Checking UCE-Protect here you may also understand if your IP reputation is affected by other IPs from same network

HTH,
Ioan

Thank you very much. It was a very valuable explanation. I will look at these tomorrow.
