Do you run your own MTA to transmit your messages, or is that service 
provided by someone else.  This smells to me like someone somewhere made 
some changes on the MTA to strip VERP-style "plus" addressing, and that 
may have borked your mailing lists.

If you run your own mail server, check to see if there have been any 
recent changes made on the MTA.  Check the logs of the MTA from both 
before the change and after the change, to see what the effect is.

If you don't run your own mail server, you'll need to contact the people 
that do to get them to do this analysis for you.
