Tested on almost grade A supported systems CentOS 5,6,7 , Debian 6,7,8 , Ubuntu 12.04-15.10.
On old version works perfectly now Exim4 works very strange if I want to send a message to gmail ..
SMTP error from remote mail server after end of data:
host gmail-smtp-in.l.google.com [2a00:1450:4013:c01::1a]:
xx.xx.xx [2a00:f820:50::1000:1d03:2747] Our system has detected that this
xx.xx.xx message does not meet IPv6 sending guidelines regarding PTR records

On older version works perfectly, you only need to make an upgrade (or install this new version) and your mail system won't works (in many cases of SO,will not works any SMTP protocols).
I had tested with / without Firewall, spamassasin or clamav .....
All my servers are hosted on dedicated IPs, VPS with IPv6 are settled correctly.
Can you please tell me where to find an older version installation script?
Thank you very much!

update spf record with ipv6 address and PTR record or disable ipv6 in Exim. You can search here on the forum how to disable IPV6 if you want that.
