[rt-users] Can my MTA Strip off all the replies?

[Stevo]

Okay... here's my next question. 

My users like to use the email facility to reply to tickets but their 
reply always contains the rest of the ticket's replies because they just 
hit reply in Outlook.

I use Exim as my MTA - is there a way in Exim or RT to strip off all the 
'Original Message' information when the data gets put in the ticket, so 
I just have their reply, rather than all the old information?

Know what I'm getting at?  Kinda hard to explain!
