[rt-users] non-member request creation

[Aida Escriva]

I may be overlooking something, but..

I've sucessfully installed RT and can use the web interface to create
requests. Each time I attempt to create a request as a non-member via
email I receive:

>There has been an error:
>There has been an error with your request:
>You don't have permission to create requests in this queue

I have the box labeled "Allow non-members to create request" checked in
the queue configuration. 

My aliases are as follows:

>accounting: "|/opt/rt/bin/rt-mailgate accounting correspond"
>accounting-action: "|/opt/rt/bin/rt-mailgate accounting action"

What am I doing wrong?
