Pyzor issue - error from Mailscanner but not from SA or Pyzor run directly

[Alex Crow]

Hi all,

I'm having this issue in MailScanner - when Pyzor check are run from 
within ms, I get an error in the logs:

15:37:52 Jul 31 15:37:52.686 [13270] dbg: pyzor: pyzor is available:

However, if I run as the postfix user (the one configured in 
MailScanner.conf)

spamassassin -D < /tmp/.spamassassin9936b1QieYtmp

I get pyzor working:

I am running Centos 5.5 x64 with the latest ClamAV/SA easy-install 
package from the MailScanner site installed.

Any help gratefully received.

Thanks
