Hi, postfix is configured as relay server. Other systems relay with postfix. Here i want to allow for a specific group of hosts, when they use a specific mail from address only a few specific destination domains. Other hosts should not be bothered. This is only a need to limit a group of hosts to not accidentally send out mails to other domains.
smtpd_sender_restrictions = check_sender_access hash:/etc/postfix/benachrichtigung smtpd_restriction_classes = benachrichtigung benachrichtigung = check_recipient_access hash:/etc/postfix/erlaubt, reject /etc/postfix/benachrichtigung benachrichtig...@cubewerk.de benachrichtigung /etc/postfix/erlaubt microsoft.com OK aol.com OK yahoo.com OK That works and only allows mails with mail from: benachrichtig...@cubewerk.de to above domains. How can i additionally say - and only limit sending of mails to this 3 domains, if smtp connection is from 3 local IPs? (10.8.1.1-3) ? I can not think of a way to achieve this. thank you. Stefan
