I just created my account and the activation mail from MozillaZine was marked as spam because of misconfigured SPF record.
From the message header:
Code: Select all
Authentication-Results: mx.google.com;
spf=softfail (google.com: domain of transitioning apache@mozillazine.org does not designate 2605:bc80:3010::137 as permitted sender) smtp.mailfrom=apache@mozillazine.org
