You need to include the extprograms plugin: I have, and vnf.dovecot.pipe doesn't give the error.

I am not using filter now though, so I haven't try to track down what the issue is. And you also need to add vnd.dovecot.filter to sieve_extensions (or sieve_global_extensions). Ah, yes, so I do. I only had .pipe there. While I am here, does _global_ mean that they do not need to be listed in the requires header?
No, it means it can only be used from global (administrator-controlled) scripts, like those configured for sieve_before/sieve_after. So, the normal user scripts that are uploaded through ManageSieve cannot use it when it is only listed as global.
If you want implicit availability without require, you'll need to add it to sieve_implicit_extensions=. However, such a configuration is non-standard and therefore not recommended (only to provide migration from other Sieve interpreters that didn't follow the standard very closely).
That's good, I'm working on a. Filter to restyle some html emails that I get to eliminate the white backgrounds, and filter is going to be necessary for that to work.
Something along the lines of
if allof ( header :contains "from" "someone", header :contains "to" "me". Header :contains "Subject" "Stupid HTML" ) {
if body :raw :contains "</head>" { filter :try "darkmode.sh"; } }
You could also check the content-type header, rather than inspecting the body for a tell-tale HTML tag.
darkmode.sh: #!/bin/sh sed -e '|</head>|<style>* {color:white !important; background-color: black !important; } </style></head>|'
(Not that I have even begun to test that)
I am not too familiar with sed, but as long as this script reads the raw mail from stdin and writes the modified mail to stdout, it should work.
