Helle ,
I stuck in configuring geoip blocking for roundcube access. I tried maxminddb_module, where lookup fails. geoip_module examines country code, but fails in defining condition. 
DocumentRoot /var/lib/roundcube/
...
GeoIPEnable On
GeoIPDBFile /usr/share/GeoIP/GeoIP.dat
<Directory "/var/lib/roundcube">
    Header set X-Country-Code "%{GEOIP_COUNTRY_CODE}e"
    SetEnvIf GEOIP_COUNTRY_CODE ^(DE|AT)$ AllowCountry
    Options +FollowSymLinks
    AllowOverride None
    #1 fail  Require env AllowedCountry
    #2 fail Deny from all
    #2 fail Allow from env=AllowCountry
    #3 fail <If "-n %{ENV:AllowCountry}" >
    #3 fail     Require all granted
    #3 fail </If>
    Require all granted
</Directory>
Can somebody point me out to bock ips by country code for roundcubemail?
