Building an MS-SA box

I will keep that in mind, thank you Jeff. I am not a big fan of tinydns, if
am I going to have to run dns, then I will just opt for running bind9 and
get it over with. I have not as yet seen too much of a lookup bottleneck,
but I understand what you are saying and have seen that in other instances
where we've used nscd. What I really want to get working is pipelining
within sendmail, so instead of opening a connection, and doing the work,
then closing the connection, why not create a "persistent" connection over
which I pipeline the mail to the DS host. Example, tho the current
implementation of this spambox would not make for a great candidate for
this, but we run mailers in our farm where we send boat loads of emails to a
variety of recipients from the web servers using an Ironport mailer device
as the focal point before blasting it to the world. Now, being able to
pipeline there would be a nice help.

Anyway, thanks to all who have responded. The spambox is working well, other
than clamav which still doesn't seem to be working as nothing ever gets
"tagged" a containing a virus or exploit. Not sure if this is related to my
delivery rules as being "store deliver" or not, cause I can see clamscan
doing its work on the temp working directory and signs of life in logs, etc.
Can any one confirm that a delivery option of "store deliver" would
essentially BREAK clamav?

IMHO, you are better off running a cache/slave DNS like bind or tinydns.  On
Solaris we have found that nscd can be a bottleneck, not a help.  When we
moved our web service (apache) from HP to Solaris, we were getting really
poor response until we turned off nscd.  I have it turned off on all of my
Sun boxes, including my MailScanner box.  Others may have different insight
on nscd.
