TomHey <a href="https://mastodon.bsd.cafe/tags/BSD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#BSD</a> friends! Is there a way to set up oauth2 on Dovecot for authentication? (All local Auth, no Google or Microsoft involved). Do I have to run some big chunky java blob like keycloak or is there a much lighter weight implementation in C somewhere? <a href="https://mastodon.bsd.cafe/tags/OpenBSD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#OpenBSD</a> <a href="https://mastodon.bsd.cafe/tags/dovecot" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#dovecot</a> <a href="https://mastodon.bsd.cafe/tags/opensmtpd" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#opensmtpd</a> <a href="https://mastodon.bsd.cafe/tags/oauth2" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#oauth2</a>

h3artbl33d :openbsd: :ve:The SSD in my mailserver has 19,782 power on hours (which is 825 days, little over two years) with 'just' 13 powercycles. And let me tell you, those 13 powercycles are solely because I rebooted the system (upgrade, maintenance).That is how rock-stable <a href="https://exquisite.social/tags/OpenBSD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#OpenBSD</a> and <a href="https://exquisite.social/tags/OpenSMTPD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#OpenSMTPD</a> are.

Laurent CimonJust had a huge fight with <a href="https://mastodon.bsd.cafe/tags/OpenSMTPD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#OpenSMTPD</a> about lmtp rcpt-to not expanding my aliases. I had to remove the rcpt-to but we made up and we’re in love again.This could potentially be a bug. I don’t understand enough about mail to affirm that it’s a bug though.

KarFinished 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: <a href="https://camp.crates.im/tags/openbsd" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#openbsd</a> <a href="https://camp.crates.im/tags/opensmtpd" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#opensmtpd</a>

kuijstenI've created a spamtrap filter for OpenSMTPD. If you have any dedicated traps sprinkled around or maybe some old e-mail addresses that are only used by spammers these days, you can use them to protect your other mailboxes. <a class="mention u-url" href="https://netsend.nl/opensmtpd-filter-spamtrap/" rel="nofollow noopener noreferrer" target="_blank">https://netsend.nl/opensmtpd-filter-spamtrap/</a> <a class="mention u-url" href="https://honk.netsend.nl/o/opensmtpd" rel="nofollow noopener noreferrer" target="_blank">#opensmtpd</a> <a class="mention u-url" href="https://honk.netsend.nl/o/milter" rel="nofollow noopener noreferrer" target="_blank">#milter</a> <a class="mention u-url" href="https://honk.netsend.nl/o/spam" rel="nofollow noopener noreferrer" target="_blank">#spam</a>

Omar Polo: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: <a href="https://www.opensmtpd.org/" rel="nofollow noopener noreferrer" target="_blank">https://www.opensmtpd.org/</a>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!On OpenBSD, that means a `pkg_delete opensmtpd-extra` and then install right table, for example `pkg_add opensmtpd-table-passwd` for table-passwd.<a href="https://bsd.network/tags/OpenSMTPD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#OpenSMTPD</a> <a href="https://bsd.network/tags/smtpd" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#smtpd</a>

kuijstenDoes anyone know of a good DMARC verifier for <a class="mention u-url" href="https://honk.netsend.nl/o/opensmtpd" rel="nofollow noopener noreferrer" target="_blank">#OpenSMTPD</a>?

Wilko<a href="https://social.tchncs.de/tags/opensmtpd" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#opensmtpd</a> is such a well-documented and well-written MTA. I’m currently moving my mail server set-up over to a <a href="https://social.tchncs.de/tags/guix" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#guix</a> server and retiring exim in favour of opensmtpd seems like a good call to make; at least judging from how simple the config is and how quickly I got everything up and running!

Edd BarrettOK <a href="https://mastodon.social/tags/opensmtpd" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#opensmtpd</a> aficionados. I've read the docs, but can' figure this out. Help!I send a colleague and email the other day, but he didn't get it due to some DNS-related breakage on his side.On my side this triggered an immediate: ``` ... result="PermFail" stat="Domain does not exist" ```But I didn't get any bounce email telling me that the email had been dropped.Is there a way to have opensmtpd send me an email informing me of the permfail?

Hugo 雨果Encouraging people to learn how to <a href="https://fosstodon.org/tags/selfhost" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#selfhost</a> <a href="https://fosstodon.org/tags/email" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#email</a> is nice idea. Lots to be learnt there.Pointing them to postfix is what you do if you want them to suffer.Not sure why more folks don't use <a href="https://fosstodon.org/tags/opensmtpd" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#opensmtpd</a>, which has a clear and well documented configuration format. Actually, the whole thing is really well documented and a pleasure to set up.Perhaps it's simply less well know, but at this point it's not "new" any more.
