It's not a message size limit, but a number-of-users-in-one-batch limit.
You're trying to send to too many users at one time, and tripping one of
their anti-spam filters.

The RFC says you have to accept 100 addresses in a batch. Many sites are now
taking that to mean if you try to send them 101 or 102, they'll reject you.

Answer: don't put more than  100 users to any one domain in any single
delivery batch. 

Problem: you're using sendmail, and majordomo. It doesn't break up batches
for you by default. You need to move to a more modern MLM, or use something
like bulk_mailer, that can break stuff up for you.

IMNSO opinion, I wouldn't run majordomo today. It simply isn't terribly
compatible with how e-mail has evolved. I don't know if majordomo II was
ever released, but majordomo is really long in the tooth, and this is just
one of the places where it runs into today's e-mail reality and takes it in
the teeth.
