      Port 25 is enough.

      On my network I am using Zimbra as e-mail server and because I do not have any other DNS server than the pfsense forwarder I had to set the MX records on the DNS forwarder to recieve mails. Not sure if this is your problem.

      Did you log the traffic on the firewall rule you created to make sure that SMTP traffic reaches your pfsense?

      PS: I am using dynDNS and not all mailservers send me e-mails and rcieve my e-mails. Just want to mention it even if I sure that's not your problem.

        Thanks for the answer :)

        Our MX record is configured by our ISP, and it is configured correct (we checked it just to be sure).

        I have logged the traffic on the firewall now, so we can verify that the SMTP traffic can reach our pfsense.

          @DanishDynamite:

          Hey there!

          Can someone tell us if we are doing anything wrong?

          Example:

          TDCNET TCP * * TDCNET address 25 (SMTP) 192.168.1.254 25 (SMTP) SMTP til Exchange Server

          Whats your wan firewall rule look like?

            I am not sure what rule you mean, so therefor, i am gonna give you all our rules ;)

            TCP * * TDCNET address 25 (SMTP) * none   SMTP Test

            TCP * * 172.16.1.11 80 (HTTP) * none

            TCP * * TDCNET address 110 (POP3) * none

            TCP * * TDCNET address 143 (IMAP) * none

              ~~So you have a port forwarding rule.

              TCP * * 192.168.11.2 25 (SMTP) * none

              I can't tell for sure whether you have a matching NAT rule?

              WAN TCP * * WAN address 25 (SMTP) 192.168.11.2 25 (SMTP)~~

              Best to set up the NAT and let it generate the matching Firewall rule (bottom of NAT GUI page)

              EDIT:  Sorry, misread your original post.  Last line above still applies though.

                Okay . Didn't realise that! Going to change our rules, so they will be generated from the NAT, since it's easier :)
                However, i doubt it will fix our problem.

                  Your rule should look like-

                  TDCNET  TCP  *  *  192.168.1.254  25 (SMTP)

                  not

                  TCP    *    *    TDCNET address    25 (SMTP)

                    You never mentioned your Port Forwardings before. Did you set those up?
                    Without an Inbound Port Forward your firewall rule never gets any traffic from WAN.

                      Yeah, we did set this up. The only difference was, that i created the rules first, and then configured the NAT. I didn't realise you could configure NAT, and then it would create the rule automaticly.

                      So now, my NAT looks like this:

                      TDCNET TCP * * TDCNET address 25 (SMTP) 192.168.1.254 25 (SMTP) Test SMTP NAT

                      And therefor it have created a rule that looks like this:

                      TCP * * 192.168.1.254 25 (SMTP) * none   NAT Test SMTP NAT

                          It seems that way. We still can't receive emails, but we can see that we get trough the firewall now, and that didn't happen before. So the remaning problem is probably at the Exchange Server.

                          Thank you so much for your help :)

                            Just had this issue. Found a post back in 2011 that said to try adding a "To" and "From" rule in the Captive Portal Menu under Allowed IP Adresses Tab.

                            I did it, and now I can receive email.
                            Why is it that my server's IP needs to be input here.
                            Of course, in PFSense 2.03 you can't place a "To" and "From" rule, you have to select a "Both" rule.
                            But this is very wierd to me. I did not select a captive portal interface during setup.
                            When I do elect to install a captive portal interface, will I have to create different selections for the captive portal, and how will that affect my email server routing.
