Questions about front end servers

Question

Sun Java(tm) System Messaging Server 6.1 HotFix 0.11 (built Jan 28 2005)
libimta.so 6.1 HotFix 0.11 (built 16:16:35, Jan 28 2005)
SunOS mailstor1 5.9 Generic_112233-12 sun4u sparc SUNW,Ultra-4
On a multiple servers installation, is there a way to make the front end MTA to spool the incoming mail when the destination mail store server is down?
when Poping thru mmp server, it looks like the authentication happens on the mail store server, is that correct? if so, is there a way to make it that all pop3 authentication happens on mmp server just like LMTP between MTA and the store server.

make the front end MTA to spool the incoming mail
when the destination mail store server is down?It will do this by default, assuming you're actually using the MTA, and not the "smtp proxy" that's part of the MMP.

Inbound message traffic is a "store and forward", while mail access isn't. Under normal circumstances, a message that is addressed to a user is never 'authenticated", but all mail access is.
MMP does have a "pre-auth" ability. I think that's what you're looking for.
