If you want Spamassassin to be able to add extra headers, you need to
run it from the routers rather than the ACLs. Google for
spamassassin_pipe

If you just want to add the header, you can do it natively in exim:

Stick this in your data acl:

warn set acl_m0 =
     acl        = acl_relay_countries
     condition  = ${if ! eq{$acl_m0}{}}
     message    = X-Relay-Countries: $acl_m0

Create a recursive acl as follows:

acl_relay_countries:
   warn set acl_m3 = ${if eq{$acl_m3}{}{$h_received:}{$acl_m3}}
        set acl_m2 = ${if match{$acl_m3}{\N^[^\[]+\[([^\]]+)\]\N}{$1}{}}
        set acl_m3 = ${sg{$acl_m3}{\N^[^\[]+\[([^\]]+)\](.*)\N}{\$2}}
   warn condition  = ${if match{$acl_m2}{\N^\d{1,3}(\.\d{1,3}){3}$\N}}
        !condition = ${if match_ip{$acl_m2}{+private_networks}}
        set acl_m5 = ${sg{$acl_m2}{\N^(\d{1,3})\.(\d{1,3})\.(\d{1,3})\.(\d{1,3})$\N}{\$4.\$3.\$2.\$1.zz.countries.nerd.dk}}
        set acl_m5 = ${lookup dnsdb{txt=<,$acl_m5}{${uc:$value}}{UNKNOWN}}
        set acl_m0 = ${if eq{$acl_m0}{}{$acl_m5}{$acl_m0 $acl_m5}}
   warn !condition = ${if eq{$acl_m2}{}}
        acl        = acl_relay_countries
   accept

I only briefly tested the above but it seems to work.

There should be an obfuscated exim configuration contest.
