OpenBSD 2.9 and Sophos Antivirus ?

[Michael Kaaber <kaaber@fak.hum.ku.dk>]

I run OpenBSD 2.9 and PostFix 20010228

I would like to include an E-mail Antivirus and have looked at the AMaVis.

At the University of Copenhagen where I work, we have license to the Sophos
Antivirus
and AMaVis should support the Sophos Sweep.

Sophos didn't have a version for OpenBSD.

Can I use one of those instead:

 * Sophos Anti-Virus for Linux on Intel using libc6 
  (using a.out format)

 * Sophos Anti-Virus for FreeBSD version 3+ on Intel 
  (using ELF format)

 * Sophos Anti-Virus for Linux on Intel using libc5

 * Sophos Anti-Virus for Linux on Intel using libc6

I have tryed to install 'Sophos Anti-Virus for Linux on Intel using libc6
(using a.out format)'
but when I execute the sweep program I got this error:

 # sweep
 /usr/libexec/ld.so: sweep: libsavi.so.2.-1: Inappropriate file type or
format

 Michael.
