Filtering email headers generated from internal network (Sensible?)

Is it sensible to filter extra email headers in the gateway generated from your 
internal network before it leaves your server, so that Information like...   
User-Agent:, X-Virus-Scanned:,  and those EXTRA hopps of  Received from: 
(headers........)     won't leak out, which could be a valuable information for 
a potential intruder. Moreover the trouble multiplies if a software exploit is 
realesed before patch. It is kinda Security by obscurity. But if it buys you 
some extra time to act isn't is sensible to impliment or just too paranoid?
