Many ISPs will apply different anti-spam processing rules for
different recipients. Many recipients will not be aware of any
anti-spam processing rules that are being used by the system on their
behalf, or how their actions can modify those rules.

This is an indicator that at least part of the problem may
somehow lie within Mailman, but since you're using cPanel, it's going
to be very difficult to determine where the fault may lie.
Of course, if the Topica mailing list is not hosted on the same
physical and virtual machine as the Mailman mailing lists, then there
is always the chance that anti-spam rules will be host-specific and
not applied the same between the two systems.

Again, these messages are not coming through the same system, and
the same anti-spam rules may not be applied by the recipient machines.
