I have a catch-all mailbox and would like to set up a filter/coloring
for spam messages coming to me of the form
[[:xdigit:]]{5,}[.][[:xdigit:]]{5,}@me.mydomain.com
according to the Delivered-To: or Envelope-To: headers. I suspect
they're comming from scraped message-IDs from messages I've sent
long ago.
However, often these messages don't have a To: or CC: header, so I
can't identify them with a ~C and I don't see an option for identifying
messages by the Delivered-To or Envelope-To headers.
Is there a good way to identify these messages?
Thanks!
