Sieve scripting: How to move mails from specific domains to "Junk Mail"/mark them as spam?

[rheicide]

Some unwanted mails have been getting through the spam filter so I read a bit about Sieve scripts and created the following script (Settings > Sieve Scripting > Scripts):

require "fileinto";

if anyof (
  address :domain :is "from" "example1.com",
  allof (
    address :domain :is "from" "example2.com",
    header :contains "subject" "[ad]"
  )
) {
  fileinto "Junk Mail";
  stop;
}

I used Fastmail's Sieve tester to check it against different sets of relevant headers from the actual mails I got from those domains and it passed; however, it doesn't seem to work in Stalwart.

I'm new to all this; could someone please point out to me what's wrong with my script? Thanks in advance!

You need to upload this script to your account using the ManageSieve or JMAP for Sieve protocols. The scripts you manage from the webadmin operate on the SMTP transaction and don't have access to the fileinto action.

Thank you, that makes perfect sense! I should have realized that this was a per-user thing. Probably because at the moment I'm the sole user of my Stalwart mail server, haha.

A slightly related question, if you have the time: the action of manually marking mails as spam/moving them to the "Junk Mail" folder doesn't have any effect on the server's spam filtering behavior, right?

Have a nice day!

That's correct, the spam filter is currently global and cannot be trained individually on each account.

Got it, thanks!

Where and how do I upload and activate the script? Adding the script to the UI (Settings > Scripting > System Scripts) doesn't seem to have an effect.
