Did you redact anything significant from the bounce?

I don't see the expected boundary="66728b7fa14ce3ed" parameter to the 
Content-Type: header.

I'm also surprised that the Content-Type: is text/plain and not 
multipart/report.

I don't know enough about Mailman's bounce processing to know if it will 
find and process the message/delivery-status or not.  I also question 
what Mailman would do with a temporary failure, 4.7.0.

It looks like Yahoo TempFailed the message because they don't like 
SendGrid for one reason or another.

I'm also somewhat surprised that SendGrid is returning the entire 
original message instead of just the headers.  IMHO that's a good way 
for a bounced message's content to get trapped by a spam filter.
