I have a few accounts set up on my server which can send and receive email just fine. However, I have one account which just won't receive anything.
If I send a message to the address, I get the following response.
Status: 5.2.0 Diagnostic-Code: x-unix; can't create user output file
I have read that this message may be due to using up all of your quota but it is completely empty.
The only odd thing I have noticed is in the 'edit mail and ftp users' section for the account it says Disk Quota: 50MB Quota Used: Unlimited
Can anyone suggest a solution?
Any advice appreciated.
