[qmailtoaster] Duplicate Emails From The Same Sender

[Gabriel Lai]

Hi All,
I'm having duplicates emails from the same sender (at least 3 copies), how can 
I solve this issue? when I run top command, I can see clamd is shooting very 
very high (98%), but then it will drop again.
I'm using a older version of qmailtoaster packages, install it last year till 
now didn't do any upgrade.
Please advice
Thanks!
