I have been having the worst time with sendmail and the sendmail.mc file creating the sendmail.cf. After I make changes I run the following and have the results. Please give me some pointers for this because there has to be an easier way to edit my sendmail.mc without having such problems with my .cf. . i am running RHE3 logged in as root.
[root@clj mail]# m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf
