Re: dovecot restart

[Greg Troxel <gdt%lexort.com@localhost>]

I also use certbot's hooks, and that has led me to document (as comments
in my private script) what needs restart, what needs reload, and what
doesn't need anything.

I think it's a bug if a daemon needs to be restarted.  I think it should
stat the key/cert files periodically and reload them.   Hard to say what
the interval should be, but at least daily.

My notes say

 postfix doesn't need a restart at all

 nginx needs reload

 dovecot needs restart

and I find that dovecot restart works without a hiccup.
Specifically, timestamps on the mail from the hook script are ~2.5m
after the renewal cron job, and dovecot start times match that.
