Actually, I was thinking more of an MUA. I am still a fan of sendmail as the MTA.
Sendmail supports, postgresql, ldap, and pam, and does quite handily what I need it to do. I was thinking of possibly using tcl / openacs scripts to process the mail instead of using procmail. What would REALLY be cool is to build an openACS app to configure sendmail. Maybe just put a wrapper around the M4 files?
So, there is a mail client for dotLRN or openACS? It didn't look like that was "acs-mail-lite"?
Thanks for the input,
