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:
23: address test
23: starting :count-ge' match with i;ascii-numeric' comparator:
23: extracting to' headers from message 23: parsing address header value Kurt Jaeger dovecot@opsec.eu, dovecot@dovecot.org'
23: address value dovecot@opsec.eu' 23: address value dovecot@dovecot.org'
23: extracting cc' headers from message 23: matching count value 2'
23: with key `2' => 1
23: finishing match with result: matched
So, it looks like it is matching Reply-To and/or X-Original-To as well as To? Or is something else happening here?
23: jump if result is false
23: not jumping
24: exists test
24: header list-id' exists 24: header mailing-list' is missing
24: headers are missing
24: jump if result is true
24: not jumping
Or the logic of "not exists" has changed from AND (meaning none of those headers exist)?
26: fileinto action 26: store message in mailbox `listCC' 27: stop command; end all script execution ## Finished executing script '.active_sieve'
Headers of that message (minute received and signature headers, elided just for length)

There is one address in the To and no CC header at all, so why was this filed into listCC?
(This is the only incidence of listCC in the sieve file for the list user)
