Where are all the logs generated by qmail

I found this very interesting article:
http://mailadmin.wordpress.com/2008/11/25/authenticated-spam-detection-and-intervening-qmail/

But I can't find the log :
/var/log/qmail/smtpd/current

Where does plesk put it ?

I need to find who is connecting via SMTP and detect spammers.

Please help.

The maillog file can be found in PRODUCT_ROOT_D/var/log/maillog, which works out to /usr/local/psa/var/log/maillog on our CentOS servers.

I'm not looking maillog file, I'm looking for the following file (originallly located there):
/var/log/qmail/smtpd/current

In other words, Qmail standard instalation has many logs files, but seems plesk only uses 1 log file for qmail ?

Basically I want to find smtp log file.

One of the biggest problems I have found with qmail used on plesk, is the lack of smtp log information.

Spammers not only send spam via open-relay servers, Some spammers hack smtp accounts (considering come clients create email accounts with a very weak password), and they "legitimately", send spam via smtp connection.

The problem with plesk comes when trying to detect which email account (smtp access) is being used to send spam.

maillog is not helpful in this case.

This is a very imporant issue Plesk developers MUST consider. a way to log all SMTP connections, so you can link the delivered Email with the smtp account used to sent it. That way, plesk administrators could easily find that "80% discount on Viagra" Emails are sent using "john@myweakdomain.com" account. In that case it is just a matter of change the user password with a strong one.

I wonder if someone else has been facing this issue.
