Our ISP informs us of difficulty of messages coming from Yahoo:
Yahoo initiated a terrible policy change to their mail servers recently
that impacts every single mailing list software in use, not just Mailman.
If any Yahoo.com user posts to your list, they will cause those list
members whose ISP/ESP provider is using DMARC (Hotmail, Gmail, Bellsouth,
etc) to bounce the poster's message which can in turn cause the list to
remove these members from the list for excessive bounces. The problem is
with Yahoo. You can read more about it at:

If you are on a Yahoo account, please consider switching and resubscribing
to trijug and other lists.
