[exim] missing } in condition

Hello,

        Anyone know why this condition:

condition = ${if and {\
        {eq 
{${lookup{$sender_address_domain}lsearch{/etc/exim/ze_skrzynkami}{0}{1}}}{1}{0}{1}}\
        {eq 
{${lookup{$sender_address_domain}lsearch{/etc/exim/ze_skrzynkami}{0}{1}}}{1}{0}{1}}\
        }{1}{0}}

give this error:
"missing } at end of condition inside "and" group"

It's only for testing, so please don't look ont those streange numbers.

Thanks
Pawel R.
