It's also worth noticing that every single email contains both a web link to unsubscribe
Not sure about the header but I'm not seeing the web link in the body of the email
I just checked a -general email and the original message did not include the footer:
That's correct, it's in the header only. We had to stop adding new MIME parts to messages because it caused a large amount of the list email to be considered spam by major providers. The headers is a standard way to do it. This was outlined in the email Stephen sent about the migration.
gmail in particular sometimes shows an unsubscribe link directly based on the header and sometimes now. And they don't document exactly what the rules are to show them -- they document a minimum set (which we do now fulfill, but didn't use to), but this set is not a guarantee for gmail to actually show the link. For example in this thread the original email (the one just containing unsubscribe) *does* include a link to unsubscribe. But a fair amount of others don't. (Headers are still visible of course, but not without clicking through)
