I am also trying to implement the same for my network. We have one
account called staff and the mail sent to this address goes to all the
employees in the organisation.
I have configured main.cf as per above example
smtpd_restriction_classes = insiders_only <<<<<----------
insiders_only = check_sender_access hash:/etc/postfix/sender_access,
smtpd_recipient_restrictions = permit_mynetworks,
But still I am able to receive the mail from outside on this account
from accounts list permitted to send mail to this account.
Apart from my domain(example.com) some other email ids from which
mails are allowed to be send to this account are added to the
I am using Postfix 2.1.5 on FC3 with MailScanner.
Any pointer what can be the problem?
Thanks & Regards
