Almost there now. I found a reference online that said to add "-u spamd"
to the end of the OPTIONS line in /etc/defauls/spamassassin and that
removed the log entry...
spamd: still running as root: user not specified with -u, not found,
or set to root, falling back to nobody
The posting also said that the line...
spamd: handle_user (getpwnam) unable to find user: 'admin'
... was nothing to wory about.
Only thing left now, I think, is finding out where to change something
to remove the startup message...
Could not retrieve sendmail macro "i"! Please add it to
confMILTER_MACROS_ENVFROM
Again, thanks for your help. :)
