Auto Responder in AWK

[Graphic Rezidew]

I'm considering writing an auto-responder in AWK for qmail. 

My initial thought is to grab the 'From:' field and use it if there is 
no 'reply-to' field and then call qmail-inject. Does anyone see any 
glaring wholes thus far?


(no, using AWK doesn't count as a whole. It's still a kick arse tool. )
