I have a small network, 3 Win98 machine and a Mandrake 6.1 server. The server handles web traffic, FTP, and email. Sendmail will route the emails to the right people, but when they try to send out they get a 550 - relaying not allowed. I thought I had all the right options in ip_allow, relay_allow, relay-domain, and sendmail.cw but maybe I forgot something. A little help please?
