Dear all, hope it's going great with you.

i have successfully installed zimbra as backe end and proxy for my local network.
the proxy contains, zimbra porxy package and memcached

the bakend contains the other stuff of zimbra like mta, apache, etc. it's working fine and user can log directly or through the proxy.

now i want to allow users to send and receive message from external domains like gmail and hotmail.
only the proxy is public to internet.
my question is, which packages should i insall in the proxy so i can send and receive from gamil for example.

thanks in advance.
