I used the Red Hat 4 install on CentOS 4.4. I can receive mail just fine but I can't seem to send mail. I turned off sendmail after the Zimbra install. I do have the appropriate ports open on the box and the router. Did i miss something simple? I was running this on Ubuntu without issue before using the same setup.
Any help would be appreciated. I'm sure it's one little thing I'm missing.
I appreciate the quick response. I'm just an idiot and rushed the relay setting and put in the wrong relay. i just corrected it and now it is working fine.
