Anti green requesting mail

I think there may be a bit of a misunderstanding here!

"Anti-green" doesn't quite make sense, as green is a color, and "anti-" typically implies opposition or negation. Could you please clarify what you mean by "anti-green requesting mail"?

Are you perhaps looking for information on how to request mail that is not green in color? Or maybe you're asking about a specific type of mail that is not green, such as a particular type of envelope or package?

If you could provide more context or clarify your question, I'd be happy to try and assist you!
