I thought this was working as intended, but I have recently been getting some random messages put into this mailbox that definitely have list-ip headers (including some messages from this list) and that do not have multiple addresses. I believe this started happening on 20200922, which would hav been when I applied the most recent update to dovecot, as that is when the listCC box seemed to explode, but I do not have traces over 7 days old.
if allof (address :count "ge" :comparator "i;ascii-numeric" ["to", "cc"] ["2"], not exists ["list-id","mailing-list", "x-loop"] ) { fileinto :create "listCC"; stop;}
Headers of a message that triggered this (minus Received and signature headers, just removed for length)
This is the trace:

Or is something else happening here?
Are you sure the message below is what Sieve gets to process? The "To:" header value it is working with does not match the headers below. I don't see how Sieve could get that wrong.
23: jump if result is false 23: not jumping 24: exists test 24: header
list-id' exists 24: headermailing-list' is missing 24: headers are missing 24: jump if result is true 24: not jumpingOr the logic of "not exists" has changed from AND (meaning none of those headers exist)?
Nothing has changed:
https://tools.ietf.org/html/rfc5228#section-5.5
exists ["list-id","mailing-list", "x-loop"]
This only yields true when all of these headers exists. The "not" prefix causes this to always yield false unless all headers exists, which is probably not what you intended. You need to split this into separate exists tests.
