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/*" 
---------------------------------------------------------------

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

Warm Regards,
Mário Gamito
