is rumored to have said:
From my experience, outlook always marks the domains they don't know
as
spam.
This is approximately true, as far as I can tell. MS and Google both
have problems with their filtering that punish low-volume mail sources,
especially those with 'bursty' volume. If you want to deliver a bunch of
messages all at once to MS or Google once a month and very little else,
you can bet on trouble.
anyway you should have mail-tester to mark your sender scores as high
as
possible (10 is the best).
HOWEVER.... (putting on my grumpy ASF SpamAssassin PMC hat)
Disregard mail-tester.com's misuse of SpamAssassin. It does not reflect
the real-world use of SA and is chronically out of date, with apparently
localized scores applied to obsolete rules. This is enough of a problem
that if I see a citation of mail-tester.com in a formal SA bug report, I
will reject it as invalid by default. With a scolding.
This is particularly true for deliverability issues with major mailbox
providers. They do not use SA.
