Ask bapt@ who was the one to import it, and later abandon the idea of making it our default MTA. The reason was that it does not have a default domain setting, so it cannot handle email from cron, periodic etc. where the recipient is just a user name (usually “root”), and the devs were not willing to add that feature. I have email as far back as 2015 on the subject. DES -- Dag-Erling Smørgrav - d...@freebsd.org

Hi Vladimir, thank you for the information! I'm using drm-devel-kmod, and in fact found that 5.5.19.g20211230 works, while 5.7.19.g20220126 (committed as 0c38674b389ad on 2022-01-26) causes the failure. > You may try to checkout previous revision (444dc58f0247) to find out if > in-base > i2c is guilty or not. Assuming that the same change to use the system i2c code has been in the latest commit to the drm-devel-kmod port, this should be proven, now. ;-) These is the list of in-kernel i2c modules on my system (a Ryzen 9 5950 on an ASUS mainboard with B550 chip-set): $ kldstat -v | grep iic 68 iicsmb/smbus 67 iicbus/iicsmb 66 iichb/iicbus 65 iicbb/iicbus 64 iicbus/iic 63 iicbus/ic 213 lkpi_iicbb/iicbb 212 lkpi_iic/lkpi_iicbb 211 lkpi_iic/iicbus 210 drmn/lkpi_iic 56 iichid/hidbus Can I help debug this issue? I could re-install the latest version and boot with hw.dri.drm_debug or dev.drm.drm_debug set? Or are there other settings to get a debug log from the i2c side?

Re: Dragonfly Mail Agent (dma) in the base system
Hi Ed, thanks for raising, this is just on time for us. I'd like to describe what both cover and not cover and I would expect from a minimal MTA. I am on 12-STABLE/12.3-RELEASE. We solely use sendmail with relay via sendmail invocation or SMTP on localhost:25. Minimal configuration for scripts and applications running on hosts and jails. Our current corporate messaging service is being phased out for a new one which requires authentication via LOGIN or PLAIN and mandatory STARTTLS, previous was anonymous and unencrypted. Sendmail: The biggest problem is that authentication strictly requires Cyrus SASL, even for stupid ones like PLAIN/LOGIN, accourding to the handbook you must recompile sendmail from base with Cyrus SASL from ports to make this possible. A showstopper actually, for two reasons: 1. I don't like mixing base and ports, it just creates a messy system. 2. While this may work with hosts, when you have jails running off a RELEASE in Bastille this obviously will not work. Not going to work with sendmail easily. DMA: Disclaimer: I haven't tried, but read documentation and source code. Although it supports TLS, I don't see any of these [1], I fail to see how it verifies the peer. I have never seen something to provide the server's fingerprint to verification. It very much feels like an SSH-like approach. It does not listen, as documented, on localhost, so applications supporting SMTP only will need extra configuration to reach out to the relay host directly. Central config at MTA side not possible anymore. Although, I don't need certificate-based authentication against the relay and DMA supports it, it does not support of using a passphrase for the certificate key file like HTTPd supports through mod_ssl. Should be a no-brainer these days. Requirements for a simplistic MTA with a relay host: * Support TLS or STARTTLS through OpenSSL in base * Verify server's certificate chain against default certstore (/etc/ssl/certs) and log success/failure, e.g, sendmail does this after config * Properly rewrite FROM for local users user@localhost or even <> when delivered with sendmail executable * Accept messages on localhost:25 or a configurable loopback address in general (e.g., multihomed with cloned interface and jails) for those applications which only support SMTP (e.g., Java Mail or other programming libraries) The issues with certificates and OpenSSL in the base system I have already extensively dicussed with kevans@ [2]. I hope this can be put into consideration. Regards, Michael [1] https://www.openssl.org/docs/man1.1.1/man3/SSL_CTX_set_default_verify_paths.html [2] https://reviews.freebsd.org/D31487#710650
