Dear John,
Sure, please find full tests results here:
https://www.mail-tester.com/test-bw02eaxrt
That website is not in any way authoritative, misrerpresents
SpamAssassin scores, is running an obsolete version of SpamAssassin, and
seems to be *INCORRECTLY* claiming that some hostname in an URI in the
message resolves to an IP listed in Spamhaus' SBL. Checking the message
as provided on that page against a current SpamAssassin deployment does
not show hits on URIBL_SBL or URIBL_SBL_A, and manual checks of
www.naadac.org and naadac.org confirm that they are NOT LISTED. If you
show the "source" of the test message on that page, you will note that
it shows a hit on the rule named URIBL_BLOCKED, which indicates a gross
misconfiguration of SpamAssassin and is probably responsible for the
bogus URIBL_SBL and URIBL_SBL_A hits.
IN SHORT: mail-tester.com is a garbage site providing garbage results.
No one should trust it for anything.
We've lost a point for not having DKIM/DMARC authentication, which is
unfortunately not supported by our hosted exchange.
That is a far more likely cause for delivery problems than anything
else. There is no excuse for any commercial mail provider to not offer
it to their hosted customers.
We also lost 0.5 point for not having alt attribute in the images, so
we will add it.
Total is 7.8/10.
Note that the number on the mail-tester.com site is an invention of
mail-tester.com, an organization that can't even be bothered to keep
their SpamAssassin installation updated or to have the needed recursive
DNS resolver for SA to use. That "Total" is meaningless. The points
allotted for each element are arbitrary and basically meaningless.
The problem, when user is sending normal work e-mails, recipients are
finding those messages in the Junk Email folder. Even people with who
he was previously working before.
That has nothing to do with SpamAssassin. No reasonable SpamAssassin
deployment would score the message shown on that test page anywhere near
the standard spam threshold (5.0). SpamAssassin is not involved in how
any receiving sites choose to deliver mail, all SpamAssassin does is
provide a score. In this case that score is essentially zero, provided
SA is not misconfigured.
