Hi,

Just wanted to ask what happened to "[Dovecot]" when I saw this mail. 
Could you tell me how to find the List_ID ? I looked at the raw mail, 
but I didn't find it :

some removed stuff and anonymized...

I've actually been thinking about it almost since the beginning. It's =
just been annoying waste of space on my screen. And more importantly =
nowadays it's also breaking DKIM/DMARC signatures. So if somebody still =
uses Subject-based filtering it's about time to switch to List-ID header =
based filtering now.

Another thing I'm wondering about is if I should allow text/html parts, =
because removing them will also break the DKIM signatures. Or mainly I'd =
like to allow only multipart/alternative with text/plain + text/html, =
but I don't think I can configure Mailman to support that.
