The issue is that Yahoo publishes a rather broken DMARC email source
authentication policy so when anyone using Yahoo email posts to a mailing
list that re-sends their email it gets flagged as spam since the email came
from the mailing list's server instead of Yahoo's.

For example, I never see any of Andrew, KA2DDO's replies to threads until I
check my spam folder at the end of the month.

Recommended solution for Yahoo users: Stop using Yahoo for email.
