sendmail 8.12 and mailscanner

[Jeff A. Earickson]

Gang,

   I need to ask some dumb questions here...  I run sendmail 8.11.6 on
my mail server (Solaris 8), where mailscanner lives.  Before mailscanner,
I just had one queue to worry about, /var/spool/mqueue.  After mailscanner,
two queues (/var/spool/mqueue.in and /var/spool/mqueue).  Simple.

   I have been upgrading my client systems to 8.12.5, and dealing with the
MSP complications there (submit.cf and /var/spool/clientmqueue).  So if
I upgrade my mail server to 8.12.5, I will now have three queues.
Mailscanner only seems to watch /var/spool/mqueue and not clientmqueue.
I haven't figured out which queue (mqueue or clientmqueue) sendmail uses
for what mail, or why.  The only thing I found was "The .cf file is based
on the operation mode.  For -bm (default), -bs, and -t it is submit.cf
(if it exists), for all others it is sendmail.cf."  Hunh???  Can anbody
explain the flow of email thru these two queues?

   With 8.12.5, will I have inbound email (via ports 25 or 587) landing
in clientmqueue instead of mqueue, and thus escaping the clutches of
mailscanner?  How about for outbound email?  Why doesn't mailscanner look at
/var/spool/clientmqueue (or does it need to)?  What is going on here?
