Thoughts on differentiating PROD reports from DEV

Hi,
We're just starting to move reports to our BIP Enterprise PROD environment, and we're wondering how people are differentiating reports coming from their PROD and DEV environments?

We can obviously change the subjects of the DEV emails to say DEV, and we are hoping to be able to update the From email address that defaults for Email delivery (see my other post...).

I'm wondering what other methods have been used to help differentiate environments.



Any input is greatly appreciated.

Thanks,
Suzanne
