My problem was, that my reverse Proxy-Provider did not send the “HOST” header. Adding this solved the problem.

Kind of strange…

Greetings,

same problem here:

PHP 5.5.30-1~dotdeb+7.1
IPv6 Support => enabled
IPv6 => Yes
Apache 2
Debian OS

Get a bunch of error lines per request, downgrading to 6.0.20 decreased the number of errors but they still occur.

Trying to send a testmail via Wordfence Options fails.

Hope that helps solving the problem.

Feel free to ask if you need more details.
