SA DNS log question

[Tom Combs]

Hello,

I get the following in my log:

Jul 18 19:17:57 magnet mailscanner[28306]: Message g6INHZh17262 from
12.64.128.192 (magnet.fsu.edu) is spam according to osirusoft.com ...

My question is why is magnet.fsu.edu listed as the reverse lookup
for 12.64.128.192?  Magnet.fsu.edu is my server and it is 146.201.250.2.
Am I not be interpretting the log correctly?

Thanks, Tom Combs
