POP3 traffic stats with smartermail

[Jbwii]

I just noticed that in my statistics page it always shows all domains as having 0% pop3 traffic. I know for a fact that I have some domains with significant pop3 usage.

I am using smartermail and thought I had every thing set up correctly as smartermail and smarterstats seemed to be working fine.

Is there something I forgot to configure to get the pop3 stats to show up?

Thanks.
