    Angry HELP!!!! Exchange 2010 Receive Connector

    Ok so here is my situation as I have it now.... I am totally stumped and I could really use a little help.

    I have deployed a new Exchange 2010 server at my office,
    I am not using edge transport since I have it installed bundled with SBS 2011 so AD is running on the same box.

    Confirmed my smtp connector is working.
    Mail sent to exchange users from within the exchange environment work, whether locally or remotely.

    I have properly forwarded my MX records with our DOMAIN and an NSlookup of the CNAME that I set up for the exchange properly points to our exchange server IP.

    Sadly I have a crappy router on our network, and are using a Verizon Westell 327w, I have port forwarding setup for Terminal Services, and that works fine, I have configured port 25 to be forwarded to the exchange server behind the firewall. I also have port 443 and 80 forwarded as well, which both of those forwards seems to be working.

    I have made sure to allow anonymous permissions on the receive connector, as well as all available ip addresses.

    I can telnet in to the exchange server from inside the firewall, but not externally, which leads me to believe it is a Port forwarding issue from outside the firewall, but as I said, all my other forwards are working fine.

    EVERYTHING works except receiving mail from outside mail servers, and I have been ripping my hair out for 2 days now trying to figure it out...

    Maybe there is something specific to port 25 that is causing the issue? I even tried having the exchange server listen on another port, and change the port forwarding to divert port 25, to the alternate port on the exchange and still nothing...

    We have Verizon Business DSL, and according to the sadly inept supposed tier 2 rep I talked to, Port 25 is NOT blocked for incoming traffic.

    In the receive connector I have the permissions set to accept anonymous permissions, and the IP range is accept any email from 0.0.0.0-255.255.255.255 are there any other specific settings in the receive connector or anywhere else for that matter, that would deny access to computers outside my lan? Can someone walk me through the exact steps for setting one up just in case I am missing something?

    ANY help is greatly appreciated... I am already way over the timeframe I anticipated for deploying this exchange....

    thanks...

    Start with this - https://www.testexchangeconnectivity.com/

    Seems like an issue with port forwarding.

    Also, up the logging on the receive connector. - Configure Protocol Logging: Exchange 2010 Help

    Also run Get-ReceiveConnector | fl and post the results (do from EMS).

    I didn't run it yet as I got stumped on what it was asking for on the Exchange Web services URL it was asking for... I pointed it at my server IP, but the rest of the URL it is asking for I am unsure about.

    I havent fully implemented OWA yet. So I am not sure if it would actually workin....

    Ok here is another one...

    I received 3 emails on the exchange.
    2 from the USPS and another from a random email marketing company...

    But I still can't send from yahoo or any other widely know email providers... to my exchange addresses without it being bounced to the secondary in my MX setting.

    Nope no NDR because I have a secondary MX delivery at lower priority incase delivery to the exchange server fails so the message still delivers to my other mailserver which is hosted IMAP.

    Did the Get-ReceiveConnectors look setup properly to you?

    That looks OK.
    What test did you do? From the RCA did you do the internet inbound?
    Connector logging?

    Yep DId receive connector wizard as Internet Inbound.

    Are there any specific settings I should be looking at in the receive connector?

    As far as logging... it looks like the instructions you posted are for edge transport setups, which I do not have since I am running exchange 2010 that is installed with SBS 2011.

    Any ideas?

    I have to assume that the port is set properly to forward through my router, since every other port forward I have set up is working.

    I am not sure what my Exchange Web Services URL is....

    It says "Enter the full URL for Exchange Web Services in your environment. Typically, this will be something like https://mail.contoso.com/EWS/Exchange.asmx."

    Where would I find that? or is there more that I have to configure.
