      That's why I have changed field info warning to restart postfix daemon after changing inet protocol or ip.

      Netstat and config shows it listening on public address.

        That's why I thought it might not be relevant.  I have restarted many times.  Even rebooted pfSense.

        @marcelloc:

        Yes, postfix is receiving emails but can't forward them to the mail server, it's just queuing them. That was working perfectly prior to the update.

        Did you notice the "relay=none" in the log record?  Prior to the update it was "relay=192.168.11.2[192.168.11.2]:25"

        The relay host is set in the GUI for both domains to 192.168.11.2 and I can telnet 192.168.11.2 25 from an ssh session to pfSense without any problem.

          Now I see what you were saying.

          I changed it to listen on loopback (instead of WAN) and it started delivering both queued and new emails.

          I remembered you saying "choose at least wan loopback interfaces" when the package was very new but I have had postfix only listen on WAN since I first installed it.  That was the only way I could get it to work before this latest update.  I honestly don't remember the error I used to get if I listened on loopback.

          Why would it need both WAN and loopback?

            I've moved listening options from master.cf to main.cf on this latest update.

            I'll test it here and update interface field info to warn about this behavior.

            Thanks for your feedback.

              Without being restarted, is the postfix package somehow aware of changes in WAN IP?

              It hasn't been a problem for me but I had thought about it this past couple of days.

                It will work fine if you listen on loopback and create a nat rule from wan address to 127.0.0.1

                  no
                  Did you mean to say "nat rule"?  I've never had a NAT - just a rule: pass any source in to destination WAN net on port 25.

                  Although, I'm not using postfix for outbound.

                    This is a common setup while using carp.

                    You configure the package(squid,snort,dansguardian,etc) to listen only on 127.0.0.1 and then create a nat rule to forward lan,wan,etc Carp address to 127.0.0.1.
                    This way you keep package running on both boxes without missing inet address startup errors.

                    If you configure this way on your wan, every time it changes ip, postfix will keep working as it's listening on lo0 and pfsense will keep the forward from wan address to it.

                      Thank you, Marcello.  Your explanation was very instructive and helpful.

                      I guess I've never had a problem because I think the only time my cable IP has changed was when I rebooted pfSense - and that's very infrequent.

                        Wish OP would update the original post with newest info so I dont have to go thru 28 pages of whatever to see what the newest changes/versions/etc are of this package…

                                Hi,

                                I have multifuntion printers used for scan to email.
                                Is it possible to configure postfix/postscreen to not reply "service currently unavailable" at the first connection of these MFP without allowing them to relay to internet ?
                                I mean I don't want to add the IPs in the MyNetworks list because it also allows these IPs to relay to internet.

                                Thanks

                                  hi Marcello

                                  using this great tool and having some issues with the some good mails discarded by header checks because of mis-configured sender's server.

                                  Feb 12 15:57:11 postfix/smtpd[10780]: connect from ms1.cernerasp.com[159.140.193.46]

                                  is there an easy workaround without disabling the spam checks? thanks

                                    Best thing to do is have the admin for that mail server fix the DNS entry but you could try adding this to your Access Lists, Header section:

                                    /^From:.*@hvhc.org/ OK

                                      Hello everybody,

                                      We have postfix forwarder working for 1 year, yesterday I update pfsense from 2.0.1 to 2.1 and reinstall postfix. Today we do not receive external mails, in the maillog we have "Recipient address rejected: unverified address" in all msgs.

                                      I search the forums and change the listen interfaces to loopback and create a nat to forward the traffic on port 25 from WAN to loopback. But the problem persists.

                                      I found a topic (https://forum.pfsense.org/index.php/topic,70541.0.html) that says that I need to configure something on Recipient tab, I really don´t have anything on this tab before.

                                      My questions are :

                                      • With the update to postfix forwarder 2.10.2 pkg v.2.3.7 it is mandatory to put the list of mail in Recipients?
                                      • We work with Zimbra the  LDAP fetch can be used with non AD enviroment?

                                      Thanks a lot

                                        i did add it and it's still dropping the mail sporadically. they company is using 3rd party server with their email as sender and i keep having problems with it. emails from their onsite server are coming in fine. so that be a misconfiguraed server. is disabling helo checks bad idea? it's becoming an issue now but i dont want to open doors to hell. i have a couple other mails that are good but i think their mail servers might be misconfigured. should i scan their domain with mx tool for mx server names and add those to "helo" part of access list ?

                                          Hello Guys,
                                          I have been using Postfix Forwarder for more than a year with great success.
                                          Now I moved the Pfsense VM to another server, upgraded to 2.1 and I have this problem:

                                          Looks similar to a previous problem in this forum flow, so I tried forwarding to localhost and setting Postifx to listen on localhost but the error remains.

                                          Now I'm forwarding directly to the DMZ in order to have email delivered (yes, the real mail server listens and works on 172.16.16.20:25).
                                          I did not setup the LDAP verification of recipient since I'll leave it to the mail server (no problem with load).
                                          One more thing: I disabled anvil and always get the anvil communication error.
                                          I already removed and re-installed the forwarder 3 times with no success.
                                          Thanks for your kind attention and support

                                            Hello,
                                            I took a alook at the enrated main.cf and, as far as I know, the entire section on smtpd_recipient_restrictions should not be there since my reicipient tab is empty and this is just a relay server.

                                            Is there a way to tell the package not to write the whole section?
                                            Thanks

                                            Alberto
