Gmail & Yahoo mark mails as spam but SPF/DKIM are OK

[ninie1205]

Hi,

I have a digitalocean droplet with 2 domains attached to it and an e-mail address for each of them.
I have configured them, defined the DNS records accordingly but the e-mails are still going into the spam folder.
What am I doing wrong? The IP is not blacklisted. I have attached the header response in gmail account:

You have a IPV6 record? Add it to your spf record and create AAAA record and RDNS. Or disable IPV6 in exim.

[ninie1205]

I have already done that, the first line in exim4.conf.template is disable_ipv6 = true
Anyway, in the meantime I have played with the DNS records, I have changed the MX priority for one of the domains to 5 and now e-mails go into the inbox folder. Thank you.

GMail is marking as SPAM everything that is sent via ipv6... :(

GMail is marking as SPAM everything that is sent via ipv6... :(

Even with correct SFP? Really?

[dpeca]

Yes :(

I had a machine with everything configured correct:
- server hostname pointing to IPv4 (A record)
- server hostname pointing to IPv6 (AAAA record)
- reverse PTR record on IPv4 (pointing to server hostname)
- reverse PTR record on IPv6 (pointing to server hostname)
- correct SPF
- correct DKIM
- correct DMARC

Mail-tester score 10/10.
Server didn't send any email for a 30 days... completly new server, new IP.
And GMail marked it as SPAM :)

Then I switched to IPv4, and email started to go to Inbox... :)

People that are programming GMail SPAM filters are crazy.
Really.

On my servers, I had 2 IPV6 addresses. I add both to the SPF record and DNS records. Now everything works fine.
