I had this problem with Exchange using a pop3 interface. When sending from corvettemuseum.com to listserv.corvettemuseum.com, Exchange would always grab the message and and give me an invalid recipient message back. Maybe Dave's problem is a DNS lookup problem. That is what I suspected at the time. We have since upgraded and use the Exchange OWA now to send mail... Every thing is working correctly now. Check out how your e-mail is being sent out from the Thebotwins.com e-mail server and see if Listserv.thebotwins.com is being resolved properly to send it to listserv.
