Forum OpenACS Q&A: Response to ns_sendmail config problem

Collapse
Posted by Roberto Mello on
I got this error before in a brand new install of OpenACS and found out that the problem was with Sendmail and the machine itself. Whoever put that box together had not put the full domain name in /etc/HOSTNAME and had missed Sendmail config points.

I fixed the /etc/HOSTNAME and don`t know what else I did to get Sendmail working. Its config files are so freaking cryptic that only opening them in vi made me feel dizzy.

Telneting to your mail server from the shell and replicating what AOLserver would do is what led me to find the answers:
