Yes the A record goes in the forward zone. If 69.56.237.84 reverse
resolves to spameater.com then there should also be a forward A
record with the same ip.

Yes you can have as many A records you want. But again, I don't know
for a fact that this is your root problem. I just know I have seen
some systems deny because of lack of A records that match to PTR
records and it cant hurt to set it up correclty like this.
