Hi,

I've installed Zimbra Open on a Fedora system 1 year ago and it works great

Now i've to made some changes to the users specific configuration, i must control the mail delivering per user, some users can send mail out of the local domain and some others can't do it.

For example, i've configured the domain "succhia.it" and for this domain i've configured 5 mailboxes.

nonno@succhia.it
nonna@succhia.it
babbo@succhia.it
mamma@succhia.it
cane@succhia.it

NOw i'would like to say if i can configure zimbra or postfix (inside simbra) for enabling the mail delivery out of the domain "succhia.it" for the users nonno/mamma/cane and only local delivery inside the domain "succhia.it" for other users.
I've to implement the smtpauth feature o ther'is a solution whithout it?

thanks
Spokke
