Gmail marking email from me as spam
I run an email security&#x2F;monitoring business [0], and we hear this issue with Gmail a lot, in fact: we have been bitten by it as well during the early days.<p>The problem at hand is that it is really hard to debug situations like this. Google won&#x27;t tell you why a particular email is blocked, because that information will be immediately exploited by spammers.<p>We build our software suite because we found that mistakes in email configuration are easy to make and really hard to identify.<p>I did a quick scan of rafa.eu.org and found the following:<p>- SPF is setup [1] with a neutral &#x27;all&#x27; mechanism, which basically disables SPF for this domain. Hence, DMARC will set SPF as &#x27;pass&#x27; even though SPF did nothing here to help the spam algorithm to assess the sender.<p>- A DMARC record exists and has a valid syntax [2], but the proposition (p value) is set to &#x27;none&#x27;, which basically disables DMARC altogether. It will enable reporting, but nothing more than that.<p>- I don&#x27;t know you DKIM selector, so I can&#x27;t assess that, but make sure the DKIM signature address is aligned (using the same domain name).<p>- The TLS configuration of your email server uses a self-signed certificate and is very much outdated (it offers SSLv3 and RC4 ciphers). I used testlssh.sh [3] to check this.<p>So yes, you technically did setup TLS, SPF and DMARC, but in all 3 you have configuration errors. Running a mail server in 2019 requires a bit more work and maintenance than it used to be 10 years ago, but the reason is spammers, not Google. Remember: it is in Google&#x27;s best interest to have as few false positives, as it ultimately benefits the users. It&#x27;s just really frustrating that it is hard to figure out why Google is marking your email as spam.<p>[0] <a href="https:&#x2F;&#x2F;www.mailhardener.com" rel="nofollow">https:&#x2F;&#x2F;www.mailhardener.com</a><p>[1] <a href="https:&#x2F;&#x2F;www.mailhardener.com&#x2F;tools&#x2F;spf-validator?domain=rafa.eu.org" rel="nofollow">https:&#x2F;&#x2F;www.mailhardener.com&#x2F;tools&#x2F;spf-validator?domain=rafa...</a><p>[2] <a href="https:&#x2F;&#x2F;www.mailhardener.com&#x2F;tools&#x2F;dmarc-validator?domain=rafa.eu.org" rel="nofollow">https:&#x2F;&#x2F;www.mailhardener.com&#x2F;tools&#x2F;dmarc-validator?domain=ra...</a><p>[3] <a href="https:&#x2F;&#x2F;testssl.sh&#x2F;" rel="nofollow">https:&#x2F;&#x2F;testssl.sh&#x2F;</a>
