Also, from the commit:

QUOTE
-sendmail_enable="NONE" # Run the sendmail inbound daemon (YES/NO).

END QUOTE



QUOTE

END QUOTE

+sendmail_enable="NONE" # Run the sendmail inbound daemon (YES/NO/NONE). My guess is Matteo was after something more like the following text from your commit notes: setting sendmail_enable to NONE (which is now the default) turns all the sendmail_*_enable variables to NO In other words, documenting what is different about NONE vs. NO beyond the spelling distinction.

Even the handbook, in the section about changing MTA

Indeed the issue that I intended to raise was that, AFAIK, there is no documentation, for NONE, except if one reads and understands /etc/rc.d/sendmail. It is something that is known by people "in the know", and probably mentioned by a some online tutorials, but I don't think there is anything "official". (https://docs.freebsd.org/en/books/handbook/mail/#mail-changingmta) does not mention NONE, but explicitly sets the four variables to NO.

Thanks,
Matteo

(Side note: it seems that when this change will be integrated in some -STABLE branch, or when 14 becomes -STABLE, a large update to the relevant sections of the Handbook will be needed)
