It might be more clever to set a number closer to the real limit (360, iirc), and to actually count the number of queries made, but it's much simpler to tell people 250 is the limit than to tell them they can have as many as the like, as long as there are no more than 359 local recipients. Especially as we host some apparently remote domains. -- Ian Eiloart IT Services, University of Sussex _______________________________________________ Mailman-Developers mailing list [email protected] http://mail.python.org/mailman/listinfo/mailman-developers Mailman FAQ: http://www.python.org/cgi-bin/faqw-mm.py Searchable Archives: http://www.mail-archive.com/mailman-developers%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-developers/archive%40jab.org Security Policy: http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq01.027.htp
