[rt-users] Permission denied when replying to a ticket via mail

[Matthias Juchem]

Hi.

Yesterday I have removed some Group Rights. Today, I've got the following 
error when replying to an existing ticket via mail:

=====
Permission Denied

<Subject of my e-mail>
=====

I have to give one group the right 'ReplyToTicket', haven't I?

If yes, which group?
If no, what else?

Thank you for your help.

Best regards,
 Matthias
