Sounds unlikely. pledge is called at startup. This means that once it's
up and running it shouldn't be called again. Besides, a system restart
must've taken for the new pledge policy in the kernel to take effect,
which also implies an smtpd restarts.

My guess is that the reboot took place, rc tried to start smtpd with
the previous message as a result, and after that pkg_add was run without
starting smtpd.
