I send a few complaints daily. Sometimes they bounce. Rejection because of
wrong SPF checks is rather common, as I sport a -all. Usually it is after of
forwarding. This one is different. The message arrived right at the recipient
(kelilab):
Received: from wmail.tana.it ([94.198.96.74]:53101)

However, before delivering, they wanted to pass the message through
spamfilter.io. The result:
Reporting-MTA: dns; portale.keliweb.it
Action: failed
Final-Recipient: rfc822;[email protected]
Status: 5.0.0
Remote-MTA: dns; mx.spamfilter.io
Diagnostic-Code: smtp; 550 185.17.106.230 is not allowed to send mail from
tana.it. Please see the SPF record, with scope mfrom, identity [email protected],
and ip 185.17.106.230
185.17.106.230 is portale.keliweb.it and kelilab.it;
spamfilter.io is a professional spam filter. Is it?
Best
