What do your sendmail logs say?  I'm running IMP on Solaris 8, and the
only change I made to the default /etc/mail/sendmail.cf file is:

237c237
< O PrivacyOptions=authwarnings
---
> #O PrivacyOptions=authwarnings

Everything worked correctly before this change, but my logs were full of
warnings about user 'nobody' (webserver) sending as another user.

Let me know if you need more help and I can send you my config files.
