Hi!

Is there a possibility to block e-mails sending outside per user in
Postfix?
By default all users are able to send e-mails for any addresses but I
want to restrict particular users and allow them to send messages only
to our local accounts ie. xxxxx(a)domain.com.

I'm not sure yet whether these rectricted users should receive any
mails from outside...

Thanks in advance,

brgrds,
