Same-Preference MX Records

[Matt Prigge]

I have two incoming mail servers that Id like to evenly balance load across
and still maintain redundancy. Someone suggested offlist that I use two
same-preference MX records pointing to my servers, but I am not sure that
using same-preference MX records is an accepted practice (thus the reason
for my question). I can see quite clearly that AOL does this, but that
doesnt always mean its right. *grin* Are there any downsides to doing this?
