I did as you said Todd but the tests just zoom through in a fraction of
a second.
The reason for ipv6 message is I doubted my config which was an old
vexim one with loads of tweaks over the years so too rule that out I
migrated across to exim4u to get a fresh config and hadn't disabled ipv6
which I now have.
I am still getting lost connections though and I am a bit stumped to be
honest all logs look happy as far as I can see. Also did a complete
server reboot
