Problems with permissions in ~qscand/.spamassassin subdir

Hi,

I have an environment with the following softwares:

I have a server running:
- Fedora Core 2 + kernel 2.6.10-1.8_FC2
- netqmail 1.05 + ucspi 0.88 + daemon-tools 0.76 + patches (site lwq)
- netqmail-1.05-tls-smtpauth-20060105.patch (SMTP authentication)
- badrcptto.patch
- vpopmail 5.4.0 + sqwebmail 4.0.7 + autorespond 2.0.4 + 
ezmlm-0.53-idx-0.41 + qmailadmin 1.2.9

Today I update the mail scanning with new versions of:
- qmail-scanner-2.01 + Mail-SpamAssassin-3.1.7 + clamav 0.88.7

Then, I restarted all mail services from Qmail + spamd.

The qmail-scanner is running fine, calling spamd and clamd to scan/check 
mail messages.

PROBLEM:
It is appearing error messages about "permission denied" (Permissão 
negada) in subdir ~qscan/.spamassassin.

for /home/qscand/.spamassassin/auto-whitelist.lock: Permissão negada

Before the updating, the permissions were:
drwx------ qscand qscand /home/qscan
drwx------ qscand qscand /home/qscan/.spamassassin
and all worked fine with old versions...

I restarted the servers with root user.

The users running each server are:

I had tried to change permissions allowing "root group all access (rwx)" 
to ~qscan homedir and subdir .spamassassin (also to files into 
.spamassassin), but it didn't work.

Then, the only way to solve "temporarily" the problem was to give "rwx 
to others" to ~qscan homedir and subdir .spamassassin, and "rw to 
others" to files into .spamassassin.

I don't know how to discover the real user that needs access to 
.spamassassin, to solve this problem.

Thanks for any help...
