Can't log POP3

Hi,

In my life i've installed more (q)mail servers than i can count.
However, i was never able to get POP3 logging. Shame on me :(

qmail-send logs ok, qmail-smtpd logs ok, qmail-pop3ds logs ok,
qmail-pop3d don't.

The file /var/log/qmail/qmail-pop3d/current *exists*, but is always
empty :(

I have no explanation for this.
I use the same method for all, the permissions are ok, but... nothing :(

I wonder if someone is kind enough to help me here:

------------------------------------------------
Here is my /var/qmail/supervise/qmail-pop3d/run:

#!/bin/sh
env - PATH="/usr/local/bin:/var/qmail/bin" \
tcpserver -v -l 0 -P -H -Q -R 0 pop3 \
qmail-popup foo.netual.com \
/home/vpopmail/bin/vchkpw \
qmail-pop3d Maildir 2>&1
-------------------------------------------------

----------------------------------------------------------------
Here is my /var/qmail/supervise/qmail-pop3d/log/run:

#!/bin/sh
env - PATH="/usr/local/bin" \
setuidgid qmaill multilog t s2500000 /var/log/qmail/qmail-pop3d
----------------------------------------------------------------

-----------------------------------------------------
The pop3d logger is running:

[root@foo log]# svstat /service/*/log
/service/qmail-pop3d/log: up (pid 1706) 1282 seconds
/service/qmail-pop3ds/log: up (pid 1700) 1282 seconds
/service/qmail-send/log: up (pid 1705) 1282 seconds
/service/qmail-smtpd/log: up (pid 1703) 1283 seconds
[root@foo log]#
--------------------------------------------------------------

My ownership throught /var/log/qmail is qmaill.qmail
as in "chown -R qmaill.qmail /var/log/qmail/"

Also my permissions for the same directory are 2700 as in "chmod 2700
/var/log/qmail/*" 
---------------------------------------------------------------

---------------------------------------------------------------
One thing: i use vpopmail with authentication through MySQL and
compiled with --enable-auth-logging=y (not through MySQL)
and --enable-logging=v

The authentication logs are going to /var/log/maillog
The rest, i don't have a clue :(

My configure:

./configure --enable-qmaildir=/var/qmail
--enable-qmail-newu=/var/qmail/bin/qmail-newu
--enable-qmail-inject=/var/qmail/bin/qmail-inject
--enable-qmail-newmrh=/var/qmail/bin/qmail-newmrh 
--enable-vpopuser=vpopmail 
--enable-vpopgroup=vchkpw 
--enable-roaming-users=n 
--enable-tcprules-prog=/usr/local/bin/tcprules 
--enable-tcpserver-file=/var/qmail/control/tcp.smtp 
--enable-logging=v --enable-md5-passwords=y --enable-log-name=vpopmail 
--enable-valias=y --enable-qmail-ext=y --enable-ip-alias-domain=n 
--enable-many-domains=y --enable-learn-passwords=y --enable-auth-logging=y 
--enable-auth-module=mysql --disable-mysql-limits
--------------------------------------------------------------------------

Would someone give me a hand on this ?
I'd really appreciate it and be forever grateful.

Warm Regards,
Mário Gamito
