      This is why I would like to add a rule on my router so they can all go through the SMTP server of my ISP.
      Can you do it with your package postfix?

      I think you will need authentication for these clients.

      You can manually install and configure sasl as current version does not has this integrations on gui.

            Can you tell me if this can forward to a port besides 25? I have pfsense at work, and I run an email server at home, but Comcast just decided to block port 25. Was hoping to configure the mx records to point to my office, and it would forward all mail to my home email server.

              It will not filter based ou source ip as all your mail will have your comany address as source.

                ISSUE:
                –-----
                The postfix log db file is empty, and postfix does not or can not write to the db file.

                Location i'm looking at:  /var/db/postfix

                I have the same problem.

                Loggin is turned on
                Destination /var/log/maillog
                Update Sqlite Every minute
                /^Subject:/ WARN is in the right place

                But mail search is not working. DB is created, but it's empty ((

                Pfsense ver 2.0.2 i386

                  What you get on postfix logs? Can you see the subject warn message on logs and postfix database script on cron?

                    I've set up a new VM to try and test Postfix and some other packages.

                    2.1-BETA1 (amd64) built on Tue Apr 2 16:21:22 EDT 2013  +  Postfix 2.8.7,1 pkg v.2.3.4_1

                    Two things noticed so far:

                    • Still need to copy files as per this post: http://forum.pfsense.org/index.php/topic,50519.msg270803.html#msg270803

                    • When restarting the ESXi host and pfSense VM, Postfix doesn't pick up a change of WAN IP address.  Given error is: postfix/master[32735]: fatal: bind <old wan="" ip="">port 25: Can't assign requested address.  Probably because master.cf is being updated in /usr/local/etc/postfix/ not /usr/pbi/postfix-amd64/etc/postfix</old>

                    Edit: one more thing at start of package:

                    • postfix/postfix-script[55357]: warning: not owned by root: /var/spool/postfix

                      The two main problems noted above now seem to be fixed with the latest version for pfSense 2.1 (amd64). 
                      Thank you marcelloc.

                      The last point, about /var/spool/postfix is still there but never caused any problems.

                      Just as an aside, I also discovered that I could copy the /var/db/postfix/postscreen_cache.db file from the existing 32-bit 2.0.2 install to the new 64-bit 2.1 Beta1 install.

                      To avoid delayed delivery of all those "once every few weeks emails", I have a custom main.cf entry:```
                      postscreen_cache_retention_time = 30d

                      
Copying the postscreen_cache file saves having the new install re-learn all the whitelisted SMTP client IPs that the existing install knew about.

                          Hi All,

                          I've just updated package mailscanner-dev to v4.84.5_3 and upgraded pFsense to v2.0.3.
                          Now memory usage is very high. I don't know if it's due to package or pfsense update.
                          Postfix processes take very high memory  (screen captures of sys activity in old and new version attached).

                          Do have an idea ?

                          Thanks

                            It's a normal behavior. You have low memory machines.

                              Indeed I have 1024MB.
                              But why processes use so much memory now ?
                              This is a huge difference !

                                A strange new problem today with postfix forwarder on 2.1BETA amd64 test system.  Config hadn't changed.

                                Received the following error:

                                
postfix/smtpd[1783]: error: open /usr/local/etc/postfix/helo_check: No such file or directory

postfix/smtpd[1783]: warning: pcre:/usr/local/etc/postfix/helo_check: table lookup problem

                                EDIT:  looks like it should be "helo_check_s_"

                                  Is the per process memory usage of 200M+ normal ?

                                  I haven't used mailscanner before (just visited their website and they list some impressive installations), but for the past 6-7 years I have been running several Postfix systems using amavis to interface with antispam (spamassassin) and antiviruses (e.g. clamav) and postgrey and the overall memory usage is nowhere near those numbers …

                                    Regarding my post above about /usr/local/etc/postfix/helo_check

                                    I created a plain text file with one line similar to this:

                                    /^my.domain.com/ REJECT

                                    The error has gone away and postfix is forwarding mail again.  I have no idea why this file was suddenly wanted by postfix but it almost certainly happened after an upgrade to the latest 2.1 snap and the subsequent re-install of postfix.

                                    I also suspect the file should probably have been looked for in: /usr/pbi/postfix-amd64/etc/postfix/

                                    (The code above also stops remote SMTP clients from trying to claim they are part of my own domain.)

                                      I've included this helo check on latest version, but forgot to include folder check on it.

                                      It's fixed now.

                                      Thanks for your feedback. :)

                                          Hello Marcello,

                                          Very nice work (um trabalho extraordinario!), congrats!

                                          I would like to migrate my smtp proxy to something that
                                          is able to count emails per user per minutes or hours and
                                          be able to limit that.
                                          Can pfSense do that?

                                            I would like to migrate my smtp proxy to something that
                                            is able to count emails per user per minutes or hours and
                                            be able to limit that.
                                            Can pfSense do that?

                                            Not on current version, but postfwd can do that.
