Cannot use Exchange rules to redirect messages from my Exchange to external contatcs - Sophos Central Email Gateway

Marcelo Gladzik

Hello everyone,

All our external e-mails are receive/send by Sophos Central Email gateway and after, it delivery the messages. This is working normally as we expect. But few days ago we are facing something strange, when we make a rule on our Exchange Server to redirect messages received from a internal client to a external contact (for example: user@internaldomain.com forward to contatc@externaldomain.com) we receive a message from Sophos like this:

I will try to translate:

 

Your message was not delivered because security or safety issues. It may have been rejected by a moderator, you may only receive emails from certain senders, or another restriction prevented a delivery.
The following is an organization that rejects your message: relay-us-east-2.prod.hydra.sophos.com.

Diagnostic information for administrators:
Generating server: "our server name" Total retry attempts: 1
 
user@externaldomain.com
relay-us-east-2.prod.hydra.sophos.com
Remote Server returned '550 5.7.1 Rejected command'
 
 
 
Looks like the message goes to Sophos and Sophos reject it. We don´t know how to resolve this.
If we send a message from user@internaldomain.com to contact@externaldomain.com, the contact receives the message. If the message is from inside my organization the redirect works, if the message is from outside my organization, the redirect does not work.
 
The problem occurs only we use rules on our Exchange.
 
Thanks.
 
Marcelo.

    Can you tell me in detail how you got rules to utilize a secondary send connector?

    I'm trying to accomplish this same goal. I have an email tickets@mycompany.com that receives outside emails and forward it back out to mysystem@mycrm.com which then creates tickets in our system. The sophos email gateway is blocking this just like the OP. I've created the second send connector with a weight/cost of 2 but cannot figure out where in the rules to finish this.
