Last time I ran into some GitHub CI BS? It seemed to resolve itself (maybe some other MacPorts person kicked something? I dunno). Anyway, hopefully something similar will happen there.
Regardless, it's up to someone else with commit access to merge it.

MarcHu I've a strange problem with my #postfix #smtpd (I presume?) . Trying to send a mail trough it with #thunderbird , it fails with the error:
> Peer’s Certificate issuer is not recognized.
my cert is issued by Let's Encrypt and is not expired.
In postfix's logs I get this:
> smtpd[552582]: SSL_accept error from unknown[176.x.x.x]: -1
> smtpd[552582]: warning: TLS library problem: error:14094418:SSL routines:ssl3_read_bytes:tlsv1 alert unknown ca:../ssl/record/rec_layer_s3.c:1571:SSL
thinkberg@solene 💖 I can't believe it, again. If you ever end up in #Berlin or we meet somewhere, you will get a free meal and/or drink of your choice!

You may want to add "gsub(/\[|\]/, "", ip)" before "print ip" to handle the brackets around ipv6 addresses in maillog.

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 
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.
OpenSMTPD 7.4.0p0 is out! 
​
No new features but some bug fixes and portability improvements: https://www.mail-archive.com/misc@opensmtpd.org/msg06018.html
OpenSMTPD 7.3.0p2 is out! ​
https://github.com/OpenSMTPD/OpenSMTPD/releases/tag/7.3.0p2
It fixes a bug in the bundled copy of ASN1_time_parse that can lead to STARTTLS to fail, and backports the ENGINE removal to allow building with latest LibreSSL.
