opensmtpd: smtpd: process control socket closed

[Songbo Wang]

Hi list,

I am running Big Sur 11.7.4 and just installed OpenSMTPd from MacPorts. The daemon won’t run even with the default config.

$ uname -prv
20.6.0 Darwin Kernel Version 20.6.0: Fri Dec 16 00:35:00 PST 2022; root:xnu-7195.141.49~1/RELEASE_X86_64 i386

$ sudo smtpd -df /opt/local/etc/opensmtpd/smtpd.conf.dist
info: OpenSMTPD 6.8.0p2 starting
smtpd: process control socket closed

A more verbose output is included in the end.

I am wondering if this is related to this GitHub issue: https://github.com/OpenSMTPD/OpenSMTPD/issues/1122.
The user reports that a seemingly similar problem is resolved after upgrading the Linux kernel.

Thanks,

Songbo Wang
