Clamd::ERROR:: after TNEF expansion.

[[SOLTECSIS] Carles Xavier Munyoz Baldó]

Hello,
I have seen in my server logs that sometimes appear "Access denied"
errors from Clamd. These errors allways appears after a TNEF archive
expansion and these errors are always interpreted by MailScanner as if
the escaned files were infected.

Here you may see the logs of an example:
[...]
MailScanner[10778]: Expanding TNEF archive at
/var/spool/MailScanner/incoming/10778/u9J9iHsT003610/winmail.dat

MailScanner[10778]: Clamd::ERROR:: SKMBT_C224e16101910041.pdf/Access
denied. ERROR :: ./u9J9iHsT003610/tnefxxJw9_

MailScanner[10778]: Clamd::ERROR:: image001.png/Access denied. ERROR ::
./u9J9iHsT003610/tnefxxJw9_

MailScanner[10778]: Clamd::ERROR:: image002.png/Access denied. ERROR ::

MailScanner[10778]: Clamd::ERROR:: image004.png/Access denied. ERROR ::

MailScanner[10778]: Clamd::ERROR:: image003.png/Access denied. ERROR ::
./u9J9iHsT003610/tnefxxJw9_

MailScanner[10778]: Virus Scanning: Clamd found 4 infections

Why is happening this?
It doesn't happens with any other e-mail with attachments that are not
TNEF expandable.

It semas a permissions problem.
How can I solve it?

Greetings.
