This is a common issue; be sure to check in your firewall rules that you are allowing sendmail to go through the network. This should have been selected in the installation of Red Hat. For security purposes, all services are disabled from the network point of view, leaving them to be turned on by the Systems Administrator. To check this, you can do an ipchains -L and see all the firewall rules that are in place. If there is one for denying sendmail, remove it and then restart ipchains. Other than that, it should work fine. HTH, -- Jonathan -- Jonathan M.
