try:

As ROOT user

as ZIMBRA user
su - zimbra
zmcontrol stop

check /opt/zimbra/log/audit.log

you need to check which account have too many logins entries even at 0:00 to 6:00 am

I changed postfix config(file master.cf.in) to only listen port 587 for mail submission, everything is ok send/receive etc.. only problem now is reject_rbl_client fails to connect to any RBL server....

you can install fail2ban to monitor and ban ips trying to brute force your accounts

try:

run iostat 4 for 20 seconds and post the output
