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 <dove...@opsec.eu>,
dovecot@dovecot.org'
23: address value `dove...@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?
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: 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)?
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.
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)
