[exim] lists & string expansions

Hello.

I use the next acl for MAIL FROM:

  deny  message = You must authenticate youself before using this domain
        condition = ${if inlist{$sender_address_domain}{LOCALDOMAIN}}
        ! authenticated = *

I use macros LOCALDOMAIN because a domains list isn't expanded. E.g.:

  deny  message = You must authenticate youself before using this domain
        condition = ${if inlist{$sender_address_domain}{+local_domains}}
        ! authenticated = *

doesn't work.

Do anybody know how use lists in string expansions?
