Hi,
I installed postfix on a machine, which has been configured as a mail
relay server.
I want it to do 2 things:
A. accept requests from only trusted SMTP clients
B. accept requests that are addressed to domain2.net
Point A is achieved by adding the following to /etc/postfix/main.cf:
mynetworks = 192.168.112.0/24 127.0.0.1
smtpd_client_restrictions =
permit_mynetworks
reject
Point B is done by adding the following to /etc/postfix/main.cf:
relay_domains = domain2.net
smtpd_recipient_restrictions =
permit_auth_destination
reject
Other relevant settings in /etc/postfix/main.cf:
myhostname = www1.test.domain1.net
mydestination = $myhostname, localhost.$mydomain, localhost
mydomain = test.domain1.net
Sending an email to my yahoo email address from a trusted SMTP client is
being rejected as expected.
The SMTP client runs sendmail, which is properly configured to use the
mail relay server.
However, doing the same from the mail relay server is not being blocked
as expected.
What am I missing here? Thanks.
Perhaps surprisingly, postfix smtpd_*_restrictions only apply
to mail submitted via smtp.
