What intrigues me is the information:
2021-02-21 02:32:08 +0100 08 vps159681 SMTP-IN:000002A9: DomainKeys verification result: no signature
2021-02-21 02:32:08 +0100 08 vps159681 SMTP-IN:000002A9: DKIM verification result: no signature

As I understand it, DKIM is not being used. That’s right? I would like help.

Thanks.

I did a validation test of the email sent at https://www.mailgenius.com/ and the result was as follows:

It is not really validating the email with the generated key.

Hello Bruno,

No, that lines show that the incoming message is not signed, which is expected as the message is not from an external email address but from an internal one, that is using an authenticated session to send his message.

Now, the DKIM signature is made via PROCESSING service and you will see the lines like:

2021-02-21 02:32:08 +0100 08 vps159681 PROCESSING:001C5E8C: The message has been signed using DomainKeys
2021-02-21 02:32:08 +0100 08 vps159681 PROCESSING:001C5E8C: The message has been signed using DKIM

The best way to double check if the DKIM is well implemented is by sending a message to a Gmail / Yahoo email address and check the Authentication-Results headers added by their SMTP gateways.

HTH,
Ioan

Hello Indreias,

Thanks for the answer.

Everything seems to be set up and I don’t see what else to do.

In the case of gmail the message comes back with the following reply:

552 Mail rejected by the processing module: 5.7.1 [151.80.130.233 12] Our system has detected that this message is 5.7.1 likely unsolicited mail. To reduce the amount of spam sent to Gmail, 5.7.1 this message has been blocked. Please visit 5.7.1 https://support.google.com/mail/?p=UnsolicitedMessageError 5.7.1 for more information. m18si25220278wru.147 - gsmtp

In the case of hotmail it goes to the spam box with the following header:

Hello,

From the headers of the message received into the Hotmail test account I see that all is fine regarding SPF and DKIM:

Authentication-Results: spf=pass (sender IP is 151.80.130.233)
 smtp.mailfrom=multicoisastore.com.br; hotmail.com; dkim=pass (signature was
 verified) header.d=multicoisastore.com.br;hotmail.com; dmarc=pass action=none
 header.from=multicoisastore.com.br;compauth=pass reason=100

Now, why the messages sent from your server are still rejected (by Gmail) or placed in Spam folder (by Hotmail) you should continue to check into other place, like your sending IP reputation.

I’ve checked your IP (151.80.130.233) here and found that it is listed into UCEPROTECT Level 3 RBL and the explanation is that your IP belongs to a network (OVH, AS=16276) that have sent a high number o spam messages (Spam score = 130, level 1 listed abusers within the last 7 days = 1022).

Their recommendations are:

Please send a complaint to your provider and request they fix this problem immediately.
Think about this: You pay them so that you can use the Internet without problems;

If they are ignoring your complaint or claiming they can’t do anything, you should consider changing your provider.
There are currently about 105,000 providers worldwide, but only a few hundred make it to get listed into UCEPROTECT-Level 3.

According to the statistics measured against the mailflow of several national authorities in Germany, Austria and Switzerland, those few providers which often end up in our Level 3 are responsible for 50 - 75% of all global spam, while almost no real mail came from their networks and ranges.

HTH,
Ioan
