  • Forwarding email to external domain

    Hi there

    I am a total novice when it comes to server management full stop. I have seen some other solutions to this issue within this forum however it is still beyond my capabilities to understand fully.

    What I am trying to achieve is that is someone sends and email to [email protected] a copy gets forwarded to [email protected].

    So I went into the "exchange general tab" on exchange 2003 on my SBS server and clicked on delivery. Here is an option to forward email however I could not enter an email address only another contact on this server.

    After research I see that I have to either add a contact or add a user with the external address.

    I created a user called "remote" that in the "email addresses" tab only contains one SMTP email address which is [email protected]. I then select the user "remote" to forward mail to on the original domain.

    However, I receive no mail to the otherdomain.com only to mydomain.com

    Where am I going wrong here?

    Thanks a lot for any help that can be offered.

    You need to create a Contact, not a user.
    The new contact will have the external email address on it. You can then select the contact to forward email to.

      Re: Forwarding email to external domain

      Hi Simon

      Thanks for taking the time to help.

      I had tried to create a contact rather than a user.

      I went into "active directory users and computers" and located the list of all the users. Here I right clicked and added a contact called "remote2" and then added an SMTP email address of [email protected]

      I can now see a contact called "remote2" in the list. However when I add this under the "delivery options" of the "exchange general" tab within "server management", I still do not receive a copy of the mail to this address.

      Any further clues as to what I am doing wrong?

        Hi,

        I believe the information store updates every two hours. You could wait this amount of time and retry, or re-start it within services.msc and retry.

        Hope this helps.

          This isn't a setting that is affected by the Information Store cache time as it isn't permissions related.
          The kind of forwarding that is done by Exchange using this method actually means your server can appear to be spoofing. Therefore it is not 100% reliable. It all depends on how the originating domain is setup (which of course is out of your control).

          Message tracking will confirm if the message was forwarded or not.

            Thanks - yes I did try restarting the service to no avail.

            Message tracking - can you point me in the direction of where I may need to look to trace whether it actually got sent?

            Thanks a lot for all input.

              Simon - Thanks for correcting me there!

              ollyno1uk- Within exchange system manager, drill down through Tools and then open up message tracking. Enter the required fields to track your message.

                Re: Forwarding email to external domain

                I found the message tracking and I found that it was attempting to deliver the mail however it was getting bounced back.

                I tried to send an email from my pc via outlook and I got this error

                "A configuration error in the e-mail system caused the message to bounce between two servers or to be forwarded between two recipients. Contact your administrator."

                So I went back into the active directory and removed the contact.

                Now I get this error:

                "The e-mail account does not exist at the organization this message was sent to. Check the e-mail address, or contact the recipient directly to find out the correct address."

                However the email address does exist I can send mail to it via gmail and I can even send messages from this remote account to my inbox.

                What is going on? Any clues?

                Thanks so much for helping.

                  I resolved the issue regarding my last post and can now send email from outlook to the remote address

                  However in message tracking it still says NDR generated - can I see what the NDR is reporting anywhere? Any ideas why this would happen?

                  Thanks a lot

                    Re: Forwarding email to external domain

                    Now some emails are coming through but some are not - the ones that are not show in the message tracking as NDR.

                    Internal mail is forwarded correctly to the other domain, some external mail has come through but not all and I can see no reason for it to not?

                    thanks

                      You can't see the NDR. As I said above the forward is not completely reliable, because it makes the server look like it is spoofing. If you are seeing the NDR and some email going, then the contact is working. The problem is outside of your control.

                      I don't recommend forward to external accounts - I usually recommend that the user logs in to OWA or uses Outlook. Forwarding in the Exchange method is becoming less reliable because of the ongoing war on spam and spoofing.

                        Hi Simon

                        Thanks for the response. The issue is that I cannot access the server remotely to log into the exchange due to the firewall we use.

                        I have been advised to use this method as then I get a copy my mails forwarded to another domain that I can collect from the webserver by pop mail.

                        I have received two external emails since it has been set up. I cannot send an email from my gmail account or from another domain on my server.

                        Is there really nothing further that I can do to receive my emails?

                        Thanks a lot

                          The excuse you have been given is complete tosh.
                          I am not aware of any firewall that stops remote access to Exchange data, if it has been configured correctly.

                          The bottom line is that forwarding email to an external account is not going to be 100% reliable because of the way that Exchange does the forwarding. If you have a business requirement to have remote access email then you will need to find another way to get something reliable.

                          Simon.

                            Hi

                            It isn't really an excuse. It was advised that we would open ourselves up to exploits by doing this. As mentioned before, I am no expert and all I was hoping to do was to access mail remotely in whatever way.

                            The only method of doing this when I search online is by this forwarding approach too another mailbox that is accessed by pop3.

                            Can you offer any advice on how I should proceed or how you would proceed in my situation?

                            Thanks

                              That is very different to the problem being with the firewall that you use.
                              It is far riskier to open a PDF file than to expose an Exchange server to the Internet. As long as the server has been configured correctly, is fully patched and the limited ports are open (you only need two - SMTP (25) and HTTPS (443)) then the risk is minimal. If you are receiving email by SMTP then your server is under constant attack anyway, it is a fact of life when operating an SMTP server on the Internet.

                              Exchange 2003 is effectively a ten year old product. The method of forwarding that it uses appears to many sites as a spoof.
                              Therefore the only effective way to have access to Exchange email when remote is to use a method that accesses email directly from Exchange - I don't know how many more times I have to say that.

                              That gives you a number of options
                              - OWA
                              - OMA
                              - RPC over HTTPS
                              - Exchange ActiveSync
                              - Blackberry with a BES or BES Express server.

                              The native solutions all run over HTTPS traffic.
                              The only solution that does not require a port being opened inbound from the Internet is a Blackberry based solution.

                              If you don't have the experience, get a consultant in to set it up for you.

                              Simon.
