The output from spamassassin -t -D < In-whitelist.txt gives the
answer, I believe:
address hefg...@hkjhkjhk.onmicrosoft.com matches whitelist or
blacklist regexp: ^.*microsoft\.com$
Very sneaky. I think I can handle this one from here.
Thanks again.
Happy to be of help.
For what it's worth: *.onmicrosoft.com domains are part of free trials
of Office365 and generate almost entirely spam. I suppose one could be
a regular paying O365 customer and keep that free domain, but no one
who does that can care much about their email. Spammers have been
using those domains for years and MS really seems not to care about
the fact that they've become a de facto indication of spam.
In addition to the above, it's easy for a spammer to register something
like kajsdhfkjasghdskghlaskfhmicrosoft.com which would also be
whitelisted for you. I would recommend against using wildcard whitelist
patterns like that.
