qmail-smtpd logger

[Andrei Tihonov]

Hello,
I have question:
Can i make log for qmail-smtpd and qmail-pop3d ?
I want use not syslog, i want use file.
And i want have counters for SMTP and POP3 session (bytes, number and
other..) may be over perl script...
I attempt use: qmail-smtpd 2>&1 | tee smtpd.log
but in this case not logged <input> from remote, only <output> from
qmail-smtpd...

Can you help me ?

Thanks,
Andrei
