I started experimenting with Jason Mastaler's TMDA spam fighting tool a few days ago. It allows you to generate time-sensitive reply addresses in outgoing mail like skip+dated+1009986941.df094a@pobox.com. Many MTAs support the use of such "detail" information. I discovered that Mailman doesn't, however. This makes it impossible to use dated addresses with closed mailing lists. Any chance that Mailman will recognize such addresses in the future?
