Where can I put pop3 log

[liu zhi]

I have use splogger to write qmail log.(I just use /var/qmail/boot/proc as my 
/var/qmail/rc),and I use checkpassword to varify users.
(I use tcpserver -c 100 0 pop-3 /var/qmail/bin/qmail-popup www3.imaginechina.com 
/bin/checkpassword /var/qmail/bin/qmail-pop3d Maildir /var/qmail/bin/splogger pop3d &)
But I can't see pop3 logs in /var/log/maillog
Where is the pop3 log?
