Is it possible to de-cypher the ReplyTo of an email notification?

Is it possible to de-cypher the ReplyTo of an email notification?

Hello,

 I assume the ReplyTo header of a Zoho projects email notification somehow encodes a project+resource ids of what is being discussed (forum or todo item).

 If I am right, is it possible to de-cypher that string to get the projectId and the resourceId (message,todo,milestone)?

 Or, if I am wrong, is there another way to figure this out from an email notification?

Thanks much
