You really don't want to do this - its doing nothing like what you
think!
You do realise that a message with subject
Subject: Phone me on 01207 1263144
would match....
[Remember . is a wildcard in regular expressions]
Even if you fixed that, you would still find that both 207.126.144.32
and 127.207.126.144 would both match...
Its also pretty bad practice to do spam filtering in a system filter
because you cannot reject at that stage - you either make mail disappear
silently, or you have to generate a bounce (which since it will be aimed
at an innocent third party who has their sender address forged, puts you
in the position of the villan).
I suggest you do this in a content ACL.
And if you want to match an ip address using a regexp try something
closer to
207\.126\.1(?:4[4-9]|5[0-4])\.\d+
ideally with something else round it - like escaped [] to make the match
stronger.
