Hi All
I'm curious what others are doing to reduce spam originating from Office 365 or

For our customers, the bulk majority of spam they actually receive (over 90% of
whats delivered and more than 40% of whats blocked) now days comes from Office
365. D
information to send back to the client on what they should be
doing to resolve it.

the past few days. Going to our filtering system but also getting through to
Office 365 and Gmail accounts without any issue at all.
They are all the well written, formatted "please remit" type emails with a

if more people responded in this way to poor IP
reputation/behaviour, the offending carriers would put in more effort to
actually reducing this risk of their clients using their IPs/services to be a
problem for others.

We're Australian and the impact is low. In fact over the past 7 days, it would
had been zero false positives.
Even if it wasn't zero, a few lost emails is better than a whole heap of crypto

changed, just our IP) : Suspicious activity has been detec
