Message expiration policy question

Hello all,

I have a question with message expiration policies. With cyradm I have 
set several message expiration policies on folders, so that old messages 
are automatically pruned from the folder. It works pretty well thus far. 
But I have a question.

Does cyrus look at the received date in the message itself, or does it 
use some sort of file system timestamp (maybe creation date of the file) 
to determine which messages are "expired"?

The reason I ask is that spam often comes into the mix, and date info in 
the message header are often forged. So how does Cyrus do this?
