linuxconf will not setup sendmail so MX records that point to that server will queue mail. I get an error message saying will not relay. MX record does exist for that server.
Try upgrading to linuxconf-1.16r10 or later, and run the "Config/Networking/Server tasks/Mail delivery system/Basic/Generate etc/sendmail.cf" option. The resulting file should make use of the control file linuxconf places in /etc/mail. Please let me us know if this fixes the problem.
linuxconf is a nice program.. But since I don't like the way it sets up mail and plays around with too much off the system, I've completey removed linuxconf. I've also replaced sendmail with postfix.. Thanks! :)..
Sendmail configuration in linuxconf has now been turned off.
Closing since we don't ship linuxconf anymore.
