Forum OpenACS Development: Re: acs-mail-lite vs ns_sendmail
However, there are lots of calls to ns_sendmail throughout the toolkit, as grep will show:
find . -name "*.tcl" -print | xargs grep ns_sendmail
So, you probably need to configure a basic SMTP server on the box, and/or drop in a replacement ns_sendmail proc which does what you want.
Why doesn't your box have a local SMTP server listening on localhost anyway? AFAIK it should have one.
If there is interest in cleaning this up in the OpenACS CVS, I can post a patch.
This is a server hosted by another company that's why I do not control how email is configured there.
