Me neither - hence my puzzlement. The answer, though is, as usual,
more c*ck-up than conspiracy....

uk2.net used to host the domain that my colleague was using in MAIL
FROM - several registrar / hosting company moves ago. Recently, he
logged in to his control panel at uk2.net, and did a tidy-up -
including removing all the email aliases belonging to the
long-ago-transferred-elsewhere domain.

It seems that uk2's MXs are in a habit of doing sender verification
for domains they think they own - perhaps not such a bad thing - and
the removal of the aliases caused this verification to fail. A
temporary solution was to put the aliases back... a more permanent one
will hopefully follow from a support ticket we've raised with them -
they will forget that they used to host the domain.

Back to your regular programming....

Peter
