Hi,
How to restrict users to received outside mail (from internet) but only
from the local domain/network ?
If your goal is to restrict few addresses so that:
- they can only send mail to your own domains (domains in mydestination,
virtual_*_domains and relay_domains).
- the addresses can only be used from mynetworks (outsiders may not use
the address as sender or recipient)
then you can do it like this:
smtpd_restriction_classes =
...
internal_only
...
smtpd_sender_restrictions =
check_sender_access hash:/etc/postfix/restricted_addr
check_recipient_access hash:/etc/postfix/restricted_addr
internal_only =
# they can't relay
reject_unauth_destination
# they can only be used from mynetworks
permit_mynetworks
reject
== restricted_addr
[EMAIL PROTECTED] internal_only
local.example.org internal_only
if this is not what you want, explain your goal more clearly. it may be
easier to give examples of what is allowed and what is not. if you can
formulate the goal in a "mathematical logic" style (if blah and blah,
then allow. if blah and blah then reject. ...), do that too.
