Betreff: [exim-dev] [Bug 1696] verify_sender fails when sender's server is IPv6 only without MX record (delivered via IPv4)
https://bugs.exim.org/show_bug.cgi?id=1696

--- Comment #2 from Hans-Werner Hilse <exim-bugs@???> ---
B and C do have both IPv4 *and* IPv6 connectivity.
C is the host I'm running exim on.

I reduced the test to just A and C.
A = sender.haveyouseenthiscat.de
C = hilses.de

[root@hilses hw]# nc localhost 25
