Possibly.

Your confirmations are

Reply-To: catjuggling-request at cibolo.us
Subject: confirm <long_hex_string>

There have been reports, e.g.,
<https://mail.python.org/pipermail/mailman-users/2016-May/080805.html>,
that this Subject: triggers spam filters.

Try setting

VERP_CONFIRMATIONS = Yes

in mm_cfg.py. this will make the message have

Reply-To: catjuggling-confirm+<<long_hex_string>@cibolo.us
Subject: Your confirmation is required to join the catjuggling mailing list

That may help.
