Hi @AbdulrahumanHasardeen-6040 ，
'550 5.7.54 SMTP; Unable to relay recipient in non-accepted domain'
Is there a dedicated receive connector on Exchange server to specify the network hosts that are allowed to anonymously relay messages?
If not ,you could check this article for more details :Allow anonymous relay on Exchange servers

I have receive connectors as following screenshot, and it didn't allow me to create dedicated receive connector as is in the link "https://learn.microsoft.com/en-us/exchange/mail-flow/connectors/allow-anonymous-relay?view=exchserver-2019" because Default Frontend <Server name> conflict
Hi,
Considering that it's a public forum, I have covered the personal information in your post involved for privacy concern.
Please hide your personal information carefully. Thank you!
May I ask what method you used to send the email? Is the email sent via outlook client or OWA or via powershell？
Please refer to the following cmdlets to check that the accepted domain is successfully enabled on the server and check that the sender's email address is set correctly.
Get-AcceptedDomain | Format-Table -Auto Name,DomainName,DomainType,Default,AddressBookEnabled
Thank you for your concern, really appreciated
I tried Email sent via outlook and OWA sitting from inside the network and from outside the network,, delivery failed message immediately comes to inbox,
I can receive email from any domain,
Hi,
I apologise for the late reply.
Could you post the full screenshot without the full Domain Name?
To further troubleshoot, please refer to the following cmdlet to check that the email address with the error report is set up email address correctly .
( Please label them with easily distinguishable text when masking images)
get-mailbox administrator | fl *address*
Thanks for your reply
As you requested please check following screenshots
* Get-AcceptedDomain | Format-Table -Auto Name,DomainName,DomainType,Default,AddressBookEnabled *
* get-mailbox administrator | fl address *
* receive connector *
* send connector *
Hi，
It has been a few days and I am checking in to see how things are going on with this issue.
Does this issue have any updates?If you still have further questions or concerns, feel free to post back.
Hi,
You mean you have created receive and send connectors to route though the edge server?
It is not necessary, as edge subscription would automatically create the connectors for you.
I suppose it could cause some problems.
I would recommend that you could disable the connectors that you have created by yourself and see if that changes.
I have disabled the send connector that I have created after that. now I am able to send email outside organization but I have issue sending email to gmail because I am getting following error,
Error:- mx.google.com rejected your message to the following email addresses:

Your message wasn't delivered because the recipient's email provider rejected it.

and also I cannot receive email from outside organization
Hi，
and also I cannot receive email from outside organization.
May I ask have you published your environment to the Internet and configured the MX record points to the mail.contoso.com in the DNS?
The MX record is the necessity for internet users to send messages to users in the organization.
And please refer to the following link to set up SPF record and see if it works.
Setting up SPF record for on premise and hybrid domain setup - TechNet Articles - United States (English) - TechNet Wiki (microsoft.com)
@Aholic Liang-MSFT
Please see the following screenshot,
Type: TXT
Host/Name: anotherdomain.com
v=spf1 a:mail.mydomain.com.uk ip4:xx.xx.xx.xx ip4:yy.yy.yy.yy ~all
Is above record correct in my case?
Note: "xx.xx.xx.xx" is the public for exchange server 01 & yy.yy.yy is the public for exchange server 02
