It seems like both sendmail and exim4 are running on the machine... I'll look into that.
Sendmail (which, according to ps aux) is running as root, while exim is running as userid 109. So one could figure, semdmail can't be the permission problem... still, sendmail has pieces and maybe they run as different users. I dunno, maybe I'll replace it all with qmail (which I might be able to get working with webmail if I even want to do that), or with exim (which has an easy setup).
One thing we knew a few days ago, was the email problem existed completely outside openacs, and we found this out when I tried sending from a tclsh.
One thing, I used the unix tool "mail" to send a mail, and that worked.
Anyway, still exploring. I'm also going to look into one of Torbin's suggestions, that is to try a smarthost other than localhost, and configure acs-mail-lite accordingly.
