Just a quick addendum to Brad's response. From the point of view of the mail server rather than Mailman, There should be full circle DNS. I.e., an rDNS lookup of the server's IP address should give a host/domain name and a lookup of that name should return an A record (not a CNAME) with the same IP. Also, when sending mail, the server should identify itself in HELO with the same name. These things should be true for any mail server regardless of Mailman. Now if a mailman list is in a virtual domain, the envelope sender of messages from that list will be the virtual domain. This is fine, but if the virtual domain publishes an SPF record, it needs to specify the server's name as a permitted sender. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
