Hello,
I googled everywhere, read how-tos but can not find solution for simple
problem in postfix:
I would like to have such config:
- smtp 25/tcp; only server-server communication, only
mail receive for local domain, no relay, no send, encryption optional,
SPF, blocking 'servers' having ppp, adsl , dialup in domain name. No
auth because real remote servers always do not know credentials.
- submission 587/tcp;only send; encryption required; client->server
- smtps SSL 465/tcp;only send; encryption required; client->server
My problem is:
I do not know how to:
-make postfix only receive mail on port 25 only for local domain.
-block incoming mail from domains containing ppp, dialup or adsl string
in domain name.
have a nice day,
Zbigniew
