Hi , I am having a problem sending mail to [log in to unmask] I ran make aliases and added two lines for aliases that tells sendmail about listserv ... listserv: "|/usr/local/bin/lsv_amin /home/listserv/spool listserv" owner-listserv: "|/usr/local/bin/lsv_amin /home/listserv/spool owner-listserv" But I am getting this error when I try to send to [log in to unmask] Your message did not reach some or all of the intended recipients. Subject: Test Sent: 11/22/2005 11:28 AM The following recipient(s) could not be reached: [log in to unmask] on 11/22/2005 11:28 AM The e-mail account does not exist at the organization this message was sent to. Check the e-mail address, or contact the recipient directly to find out the correct address. <mailservername #5.1.1 smtp;550 5.1.1 <[log in to unmask]>... User unknown> Thanks Tamer
