new list

[sherbini @ s3 . scu . eun . eg]

I installed majordomo .... made a new list .. made proper aliases ... but
 when I send email to majordomo with any command it works fine and
subscribes users normally ..but when I send a message to the list I get an
error message back saying that permision denied to the listname file ...
 what could be wrong ? ... I checked all the permissions and it looks ok 
  thanks for your help ...
