Stuck where? Reducing SMTP_MAX_RCPTS from the default 500 to 10 will
increase the number of SMTP transactions between Mailman and the MTA
and will reduce the number of recipients per transaction. This in turn
will ensure that no message from your MTA to a destination domain has
more than 10 recipients.

And your MTA should be retrying those, and Yahoo will ultimately accept
them. I have seen the 421 4.7.0 [TS01] error from Yahoo in the past
even with VERPd messages with one recipient per message, but the
messages were always eventually accepted.

Perhaps you should talk to Yahoo about getting whitelisted.
