Thanks Karl. Yes indeed, the U. of Auckland does use mimecast.
(Unfortunately so, IMHO; it's a prize pain in the pohutukawa. :-) )
However my understanding was that mimecast, in the first instance,
"consults" the recipient about the message and offers choices: accept,
accept and permit sender, accept and permit domain, reject, reject and
block sender, reject and block domain. I would of course *not* have
rejected and blocked mail from tug.
I just now checked my "personal portal" wherein are given a list of
rejected messages and a list of blocked senders and domains. Nowhere
does "tug" appear.
So it's mysterious. :-( I will try to follow it up with the U. of A.
IT Services. Wish me luck! :-)
