the same in /var/log/mail

relay=local, delay=1, status=bounced (can't create user output file. 

Command output: /bin/sh: let: HD_QUOTA=*1024:

syntax error: operand expected (error token is "*1024") 

/bin/sh: line 1: [: !=: unary operator expected )

If the quota is increased so that the mail will be accepted all works fine. If the quota is decreased again, the error occurs again. I have tested this in different ways, with/without responders, Web-Quota -1, 1, xy and so on ...

I think to understand what happens - but I don´t know how to fix that.

Can anybody give me a hint where I can put in this missing factor for quota calculation? Many thanks in advance!
