+Hello everyone!\r
+\r
+One of my (few) problems right now with notmuch is around mailing lists\r
+that are copied, either as CC or BCC, on various emails that go around.\r
+My filtering inside notmuch right now doesn't catch all the messages,\r
+since the only tag I can match on is "to:foo@bar.org" and not all\r
+messages have the to rewritten.\r
+\r
+The standard for identifying mailing lists seems to be List-Id, as per\r
+RFC 2919. I can understand the desire to keep the number of headers\r
+included in the header block low, but I wonder if this might be a common\r
+enough use-case to suggest its inclusion.\r
+\r
+As a counter-argument, I can see the parallel to spam filtering which\r
+come with their own set of headers that are not special cased by\r
+notmuch, but there seems to be much more variety in headers there - as\r
+well as different user configurations.\r
+\r
+Thank you all for your help, and I'm looking forward to hearing your\r
+thoughts. (I'm not yet subscribed, so please keep me CCed to the\r
+thread.)\r
+\r
+Sincerely,\r
+\r
