marc0sFollow-up: the current bouncing reason is the poor reputation of my domain and it seems that the solution for this is not at my hands (having already put in all the technical requirements in). It's a matter of time until GMail considers my domain is good enough again (or not...).<br><br>I can confirm that because I already set up a trusted SMTP relay in place and the bounces continued, bad reputation is on the domain name, not on the IP address of my SMTP.<br><br>That's all, take care of your mail servers and be safe!<br><br><a class="hashtag" href="https://social.tenak.net/tag/smtp" rel="nofollow noopener noreferrer" target="_blank">#smtp</a> <a class="hashtag" href="https://social.tenak.net/tag/gmail" rel="nofollow noopener noreferrer" target="_blank">#gmail</a> <a class="hashtag" href="https://social.tenak.net/tag/spam" rel="nofollow noopener noreferrer" target="_blank">#spam</a> <a class="hashtag" href="https://social.tenak.net/tag/selfhosting" rel="nofollow noopener noreferrer" target="_blank">#selfhosting</a><span class=""><br><br>RE: <a href="https://social.tenak.net/objects/fd68b9bf-4150-4605-ad02-64d06ad29463" rel="nofollow noopener noreferrer" target="_blank">https://social.tenak.net/objects/fd68b9bf-4150-4605-ad02-64d06ad29463</a></span>
