But, that's not how it works.
* If it'd use gpg directly itself -> dependency
* if it can use gpg optionally, but directly, and that allows to do much more
  (essential things) -> Recommends
* if it can use gpg optionally, but directly, and that allows to do a few things
  more -> Recommends

Spamassasin, at least our one, has none of those, and at least a Suggest is
warranted for sure, IMO, maybe even Recommends.

I'll opt for the third, which just hit me as "correct solution":

How does it works for ISO installations? The answer: the ISO ships it by explictily
installing it.

So just let's do the same and add it to the dab Makefile:
https://git.proxmox.com/?p=dab-pve-appliances.git;a=blob;f=debian-10.0-pmg-64/Makefile;h=b309d8b869fb8695f8f0325dafd220016aa09454;hb=HEAD

(I'll do so and update the template)
