Hello teo,

add sendmail_enable="NONE" to /etc/rc.conf and sendmail() should no longer start.

See man rc.sendmail on how to disable it completely.

What is sendmail for

It's a full featured MTA (mail transport agent), and a very old and traditional one. For a working Unix system, you need *some* mail functionality, at the very least local delivery. FreeBSD has added dma (dragonfly mail agent) a while ago as a light-weight alternative.

how to disable it completely?

See https://docs.freebsd.org/en/books/handbook/mail/#mail-disable-sendmail

If you want to avoid installing it, as of now, you'd have to build the system yourself and have a look at src.conf(5).
