Greetings all, I hope someone can help.
I have created a Exchange 2013 multi-tenant organization, with two servers, both multi-role - CAS and Mailbox roles.
Internal mail flow is fine (external email addresses can send to the domain).
External firewall port forwards ports 443 and 25 to the Internal DAG IP address.
There are two multi-role Exchange servers that are members of the DAG.
I am able to connect to OWA and ECP via https://externalIP/OWA and https://alias.domain.com/OWA
No SSL certificates have been purchased or installed yet.
Exchange URLs have not been changed since default configuration at install.
OWA and ECP works both internal and external.
External DNS works with SPF and PTR records correctly configured
Exchange RCA - Send test only fails with one Spam Listing (this Blacklist provider now flags all domains and you cannot ask to be removed)
Send Connectors are the default ones created during install. Receive connector is standard configuration with - * -
When sending email to an external address, I receive a failure notice
ServerName.test.corp.int gave this error:
Unable to relay
Your message wasn't delivered due to a permission or security issue. It may have been rejected by a moderator, the address may only accept email from certain senders, or another restriction may be preventing delivery.
More Info -
ServerName.test.corp.int
Remote Server returned '550 5.7.1 Unable to relay'
I have been troubleshooting this for many hours with no progress.
I have created new Send Connectors for the server that is advising that it is unable to relay, but they have all failed.
I have tried setting the Internal IP address for Exhange Server 1 (Exchange Server 2 reports failure), with most combinations of Security (Anonymous, Exchange Users, etc).
I have also tried with the IP range 192.168.11.0/24 to allow the whole the subnet, I still receive the unable to relay failure notice.
I have tried this guide - hxxps://glazenbakje.wordpress.com/2012/12/30/exchange-2013-how-to-configure-an-internal-relay-connector/ - with different combinations, still no resolution.
I am at a loss as to why I can't send out with the default configuration. I would assume that email would flow out without any changes, but this does not happen.
Can someone please assist before I lose my sanity.
Thanks in advance,
Terry
