Just a note: The default value of rfc1413_query_timeout was reduced in recent versions of Exim to, I think, 5s. That was in preference to changing it to 0s, as a change to 0s would impact sites which don't change that default, something Philip doesn't like to do except when the major version changes. Philip will be retired (late September) before Exim 5 is out--the Exim community is well along in setting up a structure to deal with that. His retirement is, IMHO, much scarier with respect to the PCRE library than is is with respect to Exim. --John ------------------------------------------------------ Mailman-Users mailing list Mailman-Users@python.org http://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://www.python.org/cgi-bin/faqw-mm.py Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-users/archive%40jab.org Security Policy: http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq01.027.htp
