[rt-users] reply to a comment leads to correspondence (instead of comment)

[Vaclav Vobornik]

Hello
we are using fetchmail and "rt-mailgate --queue General --action 
correspond" to pass emails from mail box into the RT (3.8.2). 
Unfortunately, we have only one mailbox available and any email reply 
(to the same email address) to a comment (written using the web 
interface) leads to unwanted publishing of the comment.

Is there any way, how to process "[comments]" string in a subject that 
RT could process it as a comment instead of a correspondence even it is 
sent to the same email address?

I know this could be solved on a system level (e.g. procmail), but I 
would rather see it solved inside the RT...

Many thanks
