      RobinGill,

      all working now? I was trying to reproduce your no valid recipients check you've posted today.
      The reinstall did the trick?

        Hi marcelloc,

        I'm sorry if this really doesn't concern you, but I would love if you could either point me in some direction or something about this matter;
        I'm using your postfix forwarder just for relaying messages because my net is blocked, works wonderfully, but…
        I realized today that messages over just a couple of megabytes is a no-go sending through the forwarder, I upped the limit to ~100mb (102400000 bytes).
        I just tried sending a message that is just over 10 megabytes in size and I get this message:

        May 25 10:55:22 princesscelestia postfix/smtpd[3713]: NOQUEUE: reject: MAIL from twilightsparkle.fogelholk.se[192.168.11.11]: 452 4.3.1 Insufficient system storage; proto=SMTP helo= <derpy.fogelholk.se>May 25 10:55:22 princesscelestia postfix/smtpd[3713]: warning: not enough free space in mail queue: 47714304 bytes < 1.5*message size limit</derpy.fogelholk.se>

        I use the 4gb nanoBSD-image build on a usb-stick, and on the dashboard it says I have only used 17% of the total disk space, is it possible to, I don't know, use another folder or something with more space for Postfix Forwarder?
        I must admit I'm not very good with BSD-commands, but I get around somewhat and you should be able to get quite techy in your description if you decide to help me :)

        Thanks for a great addon otherwise, has worked great so far!

        Edit: Did some more testing and the error above apperently means that postfix can't allocate the 102400000 bytes that I set, if I for example decrease it to 20480000 bytes (~20mb) I can send messages larger than 10 megabytes.
        Though I would like to increase the limit to about 100 megabytes or around there, is this possible with either moving the postfix folder or where it allocates the space in some way or another?

          The problem is that /var is ram drive and /usr is read only on nanobsd.

          you can symlink postfix folder to /usr but you will need to leave /usr writable all the time.

            Alright, thanks for your answer.

            Would it be possible to give it more ram or increase the size of /var or something? The tiny beast has 2GB of total ram, and currently about 11% in use.

              Marcello,

              My SMTP Test report as follows:
              EHLO please-read-policy.mxtoolbox.com
              250-firewall.sesric.org

              I want to convert the local address (red marked) to mail2.sesric.org.
              Is there any way to solve this.

                Nahid,

                I think you just need to add

                myhostname=mail2.sesric.org
                smtp_helo_name=mail2.sesric.org

                to genereal -> custom main.cf options

                  In that case I got the following log that shows the messages were bounced and it doesn't deliver.

                    Hi Marcello,

                    Yes it's all working now that I've reinstalled. Strange thing is I tried a few times until I got it working. If I can figure out how to reproduce the problem I had I will let you know.

                    Also it's no major deal, but I'm wondering if on the next update it may be worth modifying the package to add quote marks to allow ldap authentication with a username with a space in it. I tried adding the quote marks in the gui but they are automatically removed.

                      I leave only letters and number to avoid code on the field.

                          Hi Marcelloc,

                          I have one question, some mail server is continuing sending spam email to my server.
                          It brings me a lot of useless log in Search Mail(NOQUEUE).

                          May 28 15:41:58	xxx@xxx.com	aaa@aaa.cn	reject
                          May 28 15:42:58	xxx@xxx.com	aaa@aaa.cn	reject
                          May 28 15:43:58	xxx@xxx.com	aaa@aaa.cn	reject
                          May 28 15:44:58	xxx@xxx.com	aaa@aaa.cn	reject
                          May 28 15:45:58	xxx@xxx.com	aaa@aaa.cn	reject
                          May 28 15:46:58	xxx@xxx.com	aaa@aaa.cn	reject
                          May 28 15:47:58	xxx@xxx.com	aaa@aaa.cn	reject
                          

                          I add the rule in Access List –> Sender

                          xxx@xxx.com RJECT
                          bbb.com REJECT
                          

                          But I found I still can see these log in Search Mail.

                          Can I just block these mail address somewhere? Or maybe there will have a filter for log?

                          Thanks for your great work!

                            The noqueue log means that the message was rejected before mail data.

                            To do not receive this error, you will need to configure a firewall rule for these ips.

                              In fact, I has tried this method already, however it seems it doesn't work.
                              I have pfBlocker installed, I put the spam ip into the Custom list, eg:

                              111.222.333.444/32  #xxx@xxx.com
                              

                              Then I still see the NOQUEUE log…

                                can you check on diagnostics table if this ip is listed on pfblocker alias?
                                what action did you selected on pfblocker?

                                pfBlocker is a nice package  ;), but for this rule, you need just an alias and a rule on wan.

                                  Deny Inbound

                                  I can see the packets which has been blocked by PFblocker from Dashboard..

                                    Check the log, it may be coming from more than one ip.

                                      You are right… there are three ips from one address.

                                      I blocked them all and it's now OK~

                                      Thanks for your help~

                                        Hi,

                                        In Postfix, is it possible to forward emails to specific servers depending on the recipient email address (not only on the domain) ?

                                        Thank you

                                            Hi Marcelloc,

                                            Can I add the NOQUEUE email address to Whitelist?
                                            Some of mail server can't pass 'Helo Hostname' check….

                                            As my understanding, the "access lists" will only work with QUEUE email address.

                                            Thanks in advance~
