I don't have tons of experience with UBB but my system does not use sendmail I removed it for postfix. That is not so much of a problem because I included a path for sendmail that links to postfix. All my email on that box works properly but for some reason it gives me a error with the email functions. I have the latest upgrades that I though fixed the problem...
Well I give up on it trying to use sendmail and would rather use smtp at this point. What do I need to modify at this point to remove sendmail and use smtp?
