Need confirmation on Posix/flock settings

[dnsadmin 1bigthink.com]

Hello All,

I recently upgraded with the current ClamAV/SpamAssassin tarball and 
had flock set after SpamAssassin upgrade, but I seem to remember that 
I was advised to run Posix on a 2.6x kernel.

I am running mailscanner-4.50.15-1 from RPM install and latest 
ClamAV/SpamAsassin install on CentOS 4.4, kernel 2.6.

Please confirm; I should be running locking-type = posix, correct???

Thanks,
Glenn
