IBM-R40e sm-mta [417] NOQUEUE:SYSERR (root)"localhost" unkno= wn: Invalid Argument Sendmail is trying to convert the hostname 'localhost' into an IP number. Not being able to do that is not good. You should have at least an entry for localhost in your /etc/hosts: 127.0.0.1 localhost You might also have the IPv6 equivalent: ::1 localhost and having the same information available from the DNS is quite handy: % host localhost. localhost has address 127.0.0.1 localhost has address ::1 localhost mail is handled (pri=3D5) by localhost Note: you will also tend to have entries for 'localhost.your.domain.com' -- these are fine, but not as important as the straight 'localhost' entries.
