[rt-users] Prevent Subject Lines Starting with RE: or Re: from creating tickets

[pjaramillo at kcp.com]

I won't to stop any emails with the Subject line of RE: <whatever> or Re: 
<whatever> from creating tickets?
Is this something that can be done with sendmail or rtmailgate, while 
still retaining the ability for users to create tickets via email?

Thanks,
Paul J
