[Exim] Failed to expand condition

Hi,

Could anyone tell me why my condition fails with:

2002-06-11 14:04:55 17Hk7p-00005u-00 failed to expand condition"${if and {eq
{$sender_address_domain}{mailserver.co.uk}} {eq
{$received_protocol}{razor_checked}} {no}{yes}}" for razor_check director:
subcondition in {} expected inside "and{...}" condition

The mailserver.co.uk domain is just one I'm using for testing on this
box and will be changed later.

The condition is on the following director. A message should only pass
through the razor check if it hasn't already or it has been sent from a
local address.

razor_check:
driver = smartuser
transport = razor_check_pipe
# condition = ${if eq {$received_protocol}{razor_checked}{no}{yes}}
condition = ${if and {eq {$sender_address_domain}{mailserver.co.uk}} {eq
{$received_protocol}{razor_checked}} {no}{yes}}

If I use the hashed out line instead the director works fine, but all
mails get checked and the overhead is quite large.

Any ideas gratefully received.

TIA
