The default SMTP server of telfort relay=smtp.telfortglasvezel.nl is not having a PTR reverse DNS when checking with IPV6.
Therefore most of the e-mails I am sending from my private domains end-up in SPAM folder for gmail.
Can this be added?
Best regards,
Octavian
PS. 1. More details from auth-results@verifier.port25.com
----------------------------------------------------------
"iprev" check details:
----------------------------------------------------------
Result: fail (reverse lookup failed (NXDOMAIN))
ID(s) verified: policy.iprev="2001:838:2:1::30:127"
DNS record(s):
7.2.1.0.0.3.0.0.0.0.0.0.0.0.0.0.1.0.0.0.2.0.0.0.8.3.8.0.1.0.0.2.ip6.arpa. PTR (NXDOMAIN)
- I have a SPF,DKIM and DMARC set-up correctly but still due to missing PTR the mail is most of the time in the SPAM folder of the receiver.

Hi @octavsly , can you let me know if the advice of @RS2000 to use OpenSSL has resolved the issue? Our SMTP experts told me that the issue between our outgoing smtp.telfortglasvezel.nl and Google has been resolved. However, please note that we have removed the AAAA records and that we don't support IPv6 yet (like @Kees-Jan mentioned earlier on), since abuse from IPv6 addresses is not properly captured. PTR entries are still there.
