Jonathan Kamens 86 47<p>Well, this may be a first for me... I just received, on October 17, a bounce for an email message which my system sent on August 19.<br>It was an automated DMARC aggregate report email, and therefore there's a good chance the system it was sent to belongs to a spammer and therefore weird behavior from it would not be surprising, but still, bouncing a message after two months is pretty darn weird.<br><a href="https://federate.social/tags/smtp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>smtp</span></a> <a href="https://federate.social/tags/sysadmin" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>sysadmin</span></a> <a href="https://federate.social/tags/mailHosting" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>mailHosting</span></a> <a href="https://federate.social/tags/mailServer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>mailServer</span></a> <a href="https://federate.social/tags/DMARC" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>DMARC</span></a></p>

Jonathan Kamens 86 47<p>It turns out that once you've gone through the effort of setting up a <a href="https://federate.social/tags/Postfix" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Postfix</span></a> mail server, it's Really Easy™ to add <a href="https://federate.social/tags/DKIM" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>DKIM</span></a> signing to it with <a href="https://federate.social/tags/opendkim" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>opendkim</span></a>.<br>It's also Really Necessary™ because if your server ever needs to email someone on a Gmail or Yahoo managed domain, the message may not get through if it isn't DKIM-signed.

Jonathan Kamens 86 47<p>Hello <a href="https://federate.social/tags/MailServer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>MailServer</span></a> maintainers! If you are using rbl.realtimeblacklist.com, you should be aware that as of around 4am US/Eastern this morning their domain has been parked and is returning bogus <a href="https://federate.social/tags/DNSBL" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>DNSBL</span></a> results. I suspect that the registration lapsed and a domain resale stalker snapped it up, though I can't say for certain. Perhaps it's a temporary blip that will be resolved, but you should stop using it in the meantime.<br><a href="https://federate.social/tags/SysAdmin" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>SysAdmin</span></a> <a href="https://federate.social/tags/SMTP" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>SMTP</span></a> <a href="https://federate.social/tags/EmailAdmin" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>EmailAdmin</span></a></p>
Jonathan Kamens 86 47<p>I've recently learned empirically that apparently <a href="https://federate.social/tags/DNSBL" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>DNSBL</span></a> responses that start with "127.255" indicate problems with the query or the DNSBL service rather than an actual listing for the queried host, but I can't find this actually _documented_ anywhere.<br>My best guess is that <a href="https://federate.social/tags/Spamhaus" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Spamhaus</span></a> did this first and others copied it.<br>Can anyone confirm that or, if it's wrong, point to a reference I've missed to online documentation of this?<br><a href="https://federate.social/tags/SMTP" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>SMTP</span></a> <a href="https://federate.social/tags/SysAdmin" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>SysAdmin</span></a> <a href="https://federate.social/tags/MailServer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>MailServer</span></a></p>
