ipv6 google smtp issue

Hi, I am a happy user of Chevereto for many years now and I've been recently getting errors with new users that use google as their e-mailaccount.

host gmail-smtp-in.l.google.com [2a00:1450:4013:c07::1a]
SMTP error from remote mail server after end of data:
550-5.7.1 [MYIPV6IP] Our system has detected that this
550-5.7.1 message does not meet IPv6 sending guidelines regarding PTR records
550-5.7.1 and authentication. Please review
550-5.7.1 https://support.google.com/mail/?p=IPv6AuthError for more information
550 5.7.1 . a57si1694083eda.447 - gsmtp


Is it possible to fix this somehow? I have a correct PTR record and reverse IPV4 and IPV6 dns entry when sending e-mail. Only the chevereto script somehow has issues with this.

I can't even think in a way in how this is Chevereto related. When the system sends emails it just uses PHPMailer and that library does all the thing. Most likely you need to use the right port or something like that.

If you think that is Chevereto related then try to show me how or where because I'm totally lost here :(
