I have a big problem with sending e-mails to gmail.

( echo Subject: test ; echo ; echo test ) | /usr/sbin/sendmail -Am -i -t -v user@gmail.com

Gives me error:

[2001:41d0:602:890::] The IP address sending this message does not have a PTR record setup. As a policy, Gmail does not accept messages from IPs with missing PTR records.

I have configured Reverse DNS on IPv6, but it seems like my server can't process it right.

My resolv.conf

nameserver 8.8.8.8

When I asked my server provider for help he told me that server won't answer on port 53 and it gets timeout on trying to get RevDNS.

So... what can I do to get it working? I tried so many things...

Use the command below to locate misbehaving DNS server in the reference/redirection chain:

dig +trace -x 2001:41d0:602:890::

In you case the last successful redirect seems to be from dns*.ovh.net. to avmt2.pl..
avmt2.pl. seems to be "unresponsive".

0.9.8.0.2.0.6.0.0.d.1.4.1.0.0.2.ip6.arpa. 86400 IN NS avmt2.pl.
;; Received 123 bytes from 213.251.188.134#53(dns15.ovh.net) in 60 ms
