Yeah.. procmail filter to modify the subject would satisfy me.
I'm by no means a procmail expert, but this seems to work (though [Dovecot] gets put before the Re:)
:0 fhw
- ^List-Id:.*Dovecot Mailing List { :0 fhw
- ^Subject:\/.* | formail -I "Subject: [dovecot] $MATCH" }
I realise this is a late response on this thread and is probably overly pedantic but RFC 2919 (List-Id) is clear about which bit of the List-ID: header is actually the list-id. It's the bit in angle brackets:
The List-Id header MAY optionally include a description by including it as a "phrase" [DRUMS] before the angle-bracketed list identifier. [...] For many MUAs the parsing of the List-Id header will simply consist of extracting the list identifier from between the delimiting angle brackets.
The syntax of the List-Id header follows:
list-id-header = "List-ID:" [phrase] "<" list-id ">" CRLF
So if you are going to do List-ID filtering I suggest doing it on the bit in angle brackets not the phrase part as has been done in the procmail recipe above. Thus in procmail:
:0 fhw
- ^List-Id:.*
and in sieve:
if header :contains "list-id" "
