Hello, our postfix-server is running fine and can sent mails to internal and external addresses. so what we want to do now is to restrict the access to this server through an ACL. therefore i have added two lines within /etc/postfix/access like the example: Code: ip1 OK ip2 REJECT Afterwards I have executed the command postmap /etc/postfix/access and restarted postfix with the result that no mail was delivered any more :-( Even when I load the original (working) config and start postfix with this config there is the same behaviour. There is something confusing for me within /var/log/mail.info Code: postfix/qmgr : [message-id] from: sender, size=xxx, nrcpt=1 (queue active) postfix/smtpd: disconnect client [client-ip] psotfix/smtp: [message-id] to: recipient, relay=relayhost, delay=yy, status=sent (250 message accepted for delivery) postfix/qmgr: [message-id] removed This seems to me that all the mails are deleted?! Our basic configuration is shown in the thread here http://www.howtoforge.com/forums/showthread.php?t=13200 What is the right way to introduce an ACL to postfix? Modifying the variable smtp_client_restrictions and edit the /etc/postfix/access? It would be nice if someone out there can help me. Thanks in advance!
Are there any errors in your mail log? Are the mails gone, or are they maybe in the mail queue? You can check with Code: postqueue -p
I can't find any error in our mail log. The Mail queue is empty, this is the result of the command postqueue -p Perhaps I made a mistake in my proceeding of generating an ACL: First I created a file like this one: Code: 1.2.3.4 OK 1.2.3 REJECT So only one server should be able to send mails through this postfix server. Then I executed the command: Code: postmap -q - /etc/postfix/access < file After this I have changed the parameter smtpd_client_restrictions from no value to hash: /etc/postfix/access Afterwards I restarted postfix. Is this the correct way or is there still more to do? Does such an ACL influence the parameter mynetworks?
