Hello I just loaded redhat 6.2 configured sendmail it seems to be working. I then added Listserv to the server everything seemed to go well. At least like before. However when i started listserv and sent a message this the error in the logs. 23 Jul 2000 22:09:27 From [log in to unmask]: info info * The INFO list is unknown to [log in to unmask] Your request is * being forwarded to the nearest backbone server, * [log in to unmask] -> MAIL FROM:<> 554 buildaddr: no host -> MAIL FROM:<> 554 buildaddr: no host -> RCPT TO:<[log in to unmask]> 503 Need MAIL before RCPT -> No recipient left, message aborted. what am i doing wrong. I did it the same way as last time. I think. ;-) Matthew
