Pkg exim4 users - May 2006 - SA-exim exclude outgoing mail from local users

Hi 

I am installed sa-exim with a split-config.

I went live with system on friday and I am confused about 
SAEximRunCond.

I have modified so that it monitors my local subnet.

SAEximRunCond: ${if and {{def:sender_host_address} {!eq 
{$sender_host_address}{127.0.0.1}} {!eq 
{$sender_host_address}{194.???.??.???/
25}}{!eq {$h_X-SA-Do-Not-Run:}{Yes}} } {1}{0}}

# Remove or comment out the following line to enable sa-exim
#SAEximRunCond: 1

Perhaps I don''t need to do this??

Anyway when I send a mail I notice that SA is being run on my mail.

1FffYa-0001Vz-8o SA: Debug: SAEximRunCond expand returned: ''1''
1FffYa-0001Vz-8o SA: Debug: check succeeded, running spamc
1FffYa-0001Vz-8o SA: Action: scanned but message isn''t spam: score=-
2.8 required=7.0 (scanned in 1/1 secs | Message-Id: 
4468B359.13841.1CB89A2A@dermot.mydomain.com). From 
<dermot@sciencephoto.com> (host=dione.mydomain.co.uk 
[194.???.???.??]) for someone@dial.pipex.com


Unlike other hosts in my domain, I do have a reverse IP address, but 
SA-EXIM appears to on everything . Am I missing a step?

Any help appreciated.
Thanx.
