[SLE] Sendmail help needed

I am trying to open a limited relay for sendmail 8.9. The SuSE 6.3 box is on a FQDN with an ip in the 168.58 range. The clients trying to use the mail are not on IP's that resolve with domain names and they are in the 172.16 IP range. I have added the ip 172.16 to the /etc/mail/access file and rehashed it according to directions on sendmail.org but it is still denying relay. Could someone be so kind as to offer suggestions for fixing this? -- To unsubscribe send e-mail to suse-linux-e-unsubscribe@suse.com For additional commands send e-mail to suse-linux-e-help@suse.com Also check the FAQ at http://www.suse.com/Support/Doku/FAQ/
