Hello Iam running exim-4.86.2 on my outbound server and it was working perfectly.
So i added an ipv6 address to the box just for experimental purposes and this caused problems with sending to gmail. Error i receive is : *R=dnslookup T=remote_smtp H=gmail-smtp-in.l.google.com <http://gmail-smtp-in.l.google.com> [2a00:1450:400c:c07::1a] X=TLSv1.2:ECDHE-RSA-AES128-GCM-SHA256:128 CV=yes: SMTP error from remote mail server after end of data: 550-5.7.1 [2001:43b8:0:1a:b09a:c533:6a97:be12] Our system has detected that this\n550-5.7.1 message does not meet IPv6 sending guidelines regarding PTR records\n550-5.7.1 and authentication.

Any pointers on how to get rid of this error?? -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
