The non-set-user-id root
version of sendmail used for local mail
submission employs a queue that is separate from that used by the
mail transfer agent (MTA) daemon. This separate queue is owned by
smmsp (by default). If you prefer a different
owner, you can redefine it with this confMSPQOWN
Build macro. It is used like this:
define(`confMSPQOWN', `nullmail') 
define a username
define(`confMSPQOWN', `67541') define a user by number
If you specify an owner by a positive number that is not too large,
it will usually work. If you define a name that is not in the
/etc/passwd file (or a related file such as
/etc/master.passwd), the following error will
print and the build will fail:
chown: unknown user id: nullmail
