Anyone running a shared hosting server is probably now accustomed to dealing with constant complaints about blacklisting. It’s exim’s default setup on a cPanel server to use the shared IP of the server to send email, which means that all your clients on one server are sending out email on the same IP.  All it takes is for one spammer to send out a mailing list or one customer to get hacked and run a Darkmailer script, and suddenly everyone on your server seems to be complaining about getting their mail bounced.

If you would like clamscan to remove the infected file use the –remove option in the command.

Xen VPS目前在用这个Linux 内核版本： 2.6.18-348.el5xen
升级到这个内核之后，cpanel的quotas,disk used显示正常了

可用ip数，为(IP Addresses－3)

解决办法：
在whm里面，
Software » Install an RPM
安装下zip

vi /etc/fstab   修改成下面的
LABEL=/ /       ext3    usrjquota=quota.user,jqfmt=vfsv0                0 0
LABEL=/boot             /boot                   ext3    defaults        0 0
tmpfs                   /dev/shm                tmpfs   defaults        0 0
devpts                  /dev/pts                devpts  gid=5,mode=620  0 0
sysfs                   /sys                    sysfs   defaults        0 0
proc                    /proc                   proc    defaults        0 0
LABEL=SWAP-hda2         swap                    swap    defaults        0 0
/usr/tmpDSK             /tmp                    ext3    defaults,usrquota,noauto        0 0
