Switching to Rspamd has some advantages:
* It is probably faster than SA[1] (C + Lua vs Perl)
* We can reduce the number of moving parts. Rspamd has built-in DKIM
  signing, greylisting, DMARC checking to name a few
* It doesn't just mark the mail as spam/not-spam, it gives every mail a
  score and depending on the score it does either: nothing, greylist it,
  mark it as spam or reject it[2] (more actions is available and it can
  be tweaked)
* Replies whitelisting[3]
* It supports ARC signing, which can be useful
* A cool looking WebUi :)
* ... and more[4]...

We switched for monitoring to prometheus so zabbix-agent is unwanted and
we don't want to accidently deploy it again.

Add the zabbix-agent password for luna.
