[Mailman-Users] Very busy list says send_digests failed, Too many links (fwd)

[Ivan Fetch]

HI Mark,

    Thank you for this. We will end up deleting, since the list ownere do 
not care about digests.

    I didn't realize mailman-users was initially moderating (I never got a 
"held for moderation" reply) - it's been a while - makes sense, though., 
Thank you for clearing that up.



Ivan.
