Omar Polo<p>earlier today I cut a release for (almost) all the <a href="https://bsd.network/tags/OpenSMTPD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>OpenSMTPD</span></a> tables since some files were missing in the distribution tarballs.</p><p>If you encountered issues building them before from the provided tarball, please try again :flan_hacker:​</p>
Kar<p>Finished migrating the last service to my us-east openbsd hetzner vps from the previous finland freebsd vps (for much better latency). All that's left is setting up spamd. I previously used rspamd, but I wanted to try using what was already in base. :flan_thumbs: </p><p><a href="https://camp.crates.im/tags/openbsd" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>openbsd</span></a> <a href="https://camp.crates.im/tags/opensmtpd" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>opensmtpd</span></a></p>

Omar Polo<p>:flan_announcer: I completely forgot to post about the OpenSMTPD 7.6 release! I'm so late that we also did 7.6.0p1 in the meantime, but that's only because I forgot a few files in the tarball :flan_disappointed: </p><p><a href="https://www.opensmtpd.org/" rel="nofollow noopener noreferrer" target="_blank"><span class="invisible">https://www.</span><span class="">opensmtpd.org/</span><span class="invisible"></span></a></p><p>Among a few goodies, please remember to update the external tables if you're using any. The OpenSMTPD-extras package was split into per-tables repositories, and the communication protocol was changed. Once the executables are updated, no further changes are needed!</p><p>On OpenBSD, that means a `pkg_delete opensmtpd-extra` and then install right table, for example `pkg_add opensmtpd-table-passwd` for table-passwd.</p><p><a href="https://bsd.network/tags/OpenSMTPD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>OpenSMTPD</span></a> <a href="https://bsd.network/tags/smtpd" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>smtpd</span></a></p>
