[Exim] ClamAV Errors

Hi all

I am new to exim and exiscan and am having a little trouble. Whenever i
try to send an e-mail from outlook express on a workstation i get the
following error message.

Error 451 Temporary local error

I have checked in exim's main log and found the following error


temporarily rejected by exiscan(): Temporary local problem (error
parsing returned output)

Can anyone shed some light on my problem please

I am running Exim-4.14 with exiscan revision 26
I have the clamAV daemon running and only appear to get these problems
when Virus scanning is turned on.
