Hi Matthew,

1. check your network to have port connections to www.mailcorp.uni.me open (no firewalls on the network, no Windows firewall to block port 25 on the local machine) Also check your recv log files to have incoming connections.

2. check your receive connector to accept mails from your internet source for the specific host ; please see https://technet.microsoft.com/de-de/library/aa998618%28v=exchg.150%29.aspx  . You also may use the EAC to configure it, for support please provide the output of get-receiveconnector <your SMTP frontend> | fl

3. to get more support please let us know more details about your mailflow design:

a. is Exchange published to the internet directly (not recommended) so you need to accept mail from any source to local delivery?

b. do you receive your mail from a local /provider relay (dependency for remoteIP) ?

c. do you need additional requirements like encrypted connection, etc?

Regards,

Martin

Hi Matthew,

your drawing does not include how to connect from your ISP side to your Exchange plattform. Is there a port forwarding enabled on the 1841 Home basic router for port 25? From the drawing I think there is a MX entry fpr mailcorp.uni.me like that

mailcorp.uni.me MX 100  mail.mailcorp.uni.me

and that one, mail.mailcorp.uni.me,  is currently pointing to your router - not directly to the Exchange server.

If so, you still must create a forwarding for port 25 to your Exchange server , i.e. 192.168.0.19 port 25 ; as long as you are on a private network with your exchange, there is some additional forward required to get connected to your Exchange servers. Please also add one for port 443 if you like to connect from external Outlook / ActiveSync clients.

Please consult your routers documentation on how to do that.

When done, you still need to create a receive connector for your internet provider. Please find detailed instructions on https://technet.microsoft.com/en-us/library/jj657447%28v=exchg.150%29.aspx ;  please also check https://technet.microsoft.com/en-us/library/jj673037%28v=exchg.150%29.aspx - please ensure you set a value to the RemoteIPRange , so you prevent your server from being an open relay.

After you completed port forwarding and setting up a receive connector, mails should be received.

As a last step you need to create a send connector, https://technet.microsoft.com/de-de/library/jj657457%28v=exchg.150%29.aspx ; that step can be done independent from a working receive connector.
To do that you need to know if you must use your providers smtp relay server, and - if required - a user name and password as well as some information if you must use TLS etc. to send using that relay.

Please create SPF records in your providers DNS also, so you prevent your sending Exchange server (your routers IP) from being blacklisted.

Please let me know if it worked for you. 

Regards,
Martin
