| |To test this have then send 2 commands in one message to LISTSERV@... | |message: THANKS | INFO listname | |They should get 2 responses. If the get only a response to the second command |(INFO about &LISTNAME) then this is the problem. The reply to the THANKS |command is sent with a MAIL FROM:<> the reply to the INFO is sent with |MAIL FROM:<owner-listname@...> If they got no response from EITHER, then it is possible list messages are distributed via a different route ("backbone") than LISTSERV command responses and there might be filtering (anti-spam) rules between the list host and the list-owner's host, or possibly other problems like DNS (caching). This is where the fun begins. /Pete
