So Mailman is delivering to postfix for ALL recipients, and Postfix
can't deliver the mail to external domains, but it tries. This
certainly seems like a pure Postfix or beyond issue to me.

This and similar log entries

Apr 29 20:45:01 www postfix/qmgr[14988]: E82BA16BA31:
to=<lissa***l at yahoo.com>, relay=none, delay=35229, status=deferred
temporarily suspended: connect to yahoo.com[]: server
connection without sending the initial SMTP greeting)

say to me that either yahoo is not accepting connects or just doesn't
like you, BUT there is some Postfix/DNS issue here. The address is in the A record for yahoo.com, but it is not
associated with any of the MX names for the yahoo.com domain. Postfix
should be connecting to the MX servers for a domain and only
connecting to the A address if there are no MX records.

Are you sure you can mail directly to yahoo.com via the same Postfix?
Is your direct mail connecting to the same IP and port as Mailman is?
(Mailman is connecting to 'localhost' port 25 unless overriden by
SMTPHOST/SMTPPORT in mm_cfg.py.)
