[Exim] mx on exim (dns,mta)

MX means mail exchange right?

I only have 1 mx which is "MX 0" if i would setup another MX would it mean
i'll have another MX/MTA right? but how about when my 1st mx is down, what
will happen to those email that is on the second MX? will i still retrieve
it?

Am planning a second MX which is using exim again, is there any
config/settings i should add on the secondary Exim server?
