There are no local users so it will be all domains that are listed in relay_domains
The only reason I am going with /etc/postfix/access is because it seemed that was the correct file to use Unlisted IPs access to send mail thru this server (you have asked me not to use words like relay) This is an internal device forward mail to other internal mail systems or to our internet facing gateway. So any IPs listed can send anywhere but IPs not listed in the access file cannot -----Original Message----- From: owner-postfix-us...@postfix.org [mailto:owner-postfix-us...@postfix.org] On Behalf Of Noel Jones Sent: Thursday, May 19, 2016 1:46 PM To: postfix-users@postfix.org Subject: Re: postfix ignoring access file?

Unlisted IPs are denied access to where? Can unlisted IPs send mail to your local users? Normally, internet-facing mail servers accept mail from anywhere to the local users, and only local machines can send to anywhere. This is the mynetworks parameter, which has a different format. See docs. Some private/internal mail servers may limit incoming mail to only specific peers. The listed peers may be subdivided into those authorized to send mail to only specific destinations (usually local) or to anywhere. This is handled by some combination of mynetworks and smtpd restrictions. The details depend on the exact requirements. So what are your requirements? -- Noel Jones
