Hello I have setup for testing purposes an Exchange 2013 CU5 on a 2012R2 which is also DC and DNS.Network wise I have two virtual interfaces one for the internal network (10.10.10.x/24) and another one linked to the Ethernet physical interface of my computer which gets its properties from DHCP (usually my gateway router).
Everything seem to work normally but when I try to send emails to the outside world I only get a copy of it inside the Drafts folder. :-)
I thoroughly checked the DNS service (inside the Exchange too), A, PTR records and SOA, I tested the DNS server and nslookuped some internet addresses all resolving fine.The DNS service registers both interfaces DNS servers (the internal one which is the DC and the external one which comes through DHCP).
Through Test-ServiceHealth in Exchange Management Shell I checked all required services are up and running.
With Setspn -Lhostname I verified all required services are registered correctly on my server.
I also checked Event Viewer and besides some performance counters errors about exchange nothing else in there too.
I haven't registered an MX record because I don't need to receive mail just to send in that early stage.Am I right in that?
Any ideas are welcome and thanks in advance.
