You can't delete the file because that requires modifying the directory containing it, i.e. /var/mail/ and you don't have permissions for that. These are the permissions you showed us... ls -la /var/mail/ drwxrwsr-x 2 root mail 4096 28. Okt 15:12 *.* drwxr-xr-x 13 root root 4096 2. Sep 18:37 *..* -rw-rw---- 1 myusername mail 2090109 28. Okt 15:02 myusername So /var/mail/ has owner 'root', group 'mail', and isn't writeable by others. You do have permission to modify the contents of file 'myusername' as you are the owner, and owner has write permission set. -- Tixy
