Activating a Receive Connector consists of two parts:
1. Add a Receive Connector in Exchange/O365.
2. Provide MX tenant record to Hoxhunt
What is a Receive Connector?
In some scenarios Hoxhunt may need to bypass additional filtering systems (e.g. email scanners) that might affect normal mail flow to your mail server. Receive Connector is a feature that makes it possible for Hoxhunt to send simulation emails directly to your email system (e.g. O365 or on-premise Exchange). Receive Connector is also always recommended for hybrid environments to minimise mail flow issues.
IMPORTANT: Although it's possible to bypass many filter systems via whitelisting, Hoxhunt recommends building a Receive Connector. For more information on whitelisting different filter systems, please check our Knowledge base or contact your system provider.
Figure 1: Receive Connector is configured at "OFFICE365" to let "HOXHUNT" bypass other systems in the way.
1. Add a Receive Connector in Exchange
- Go to Exchange Admin Center.
- Select Mail Flow.
- Select Connectors and click the "+" icon.
- Select “what type” of connector you need (Mail flow Scenario). Select “Partner organization” from the “From” field, and "Office 365" from the "To" field.
NOTE: If you are configuring receive connector for an on-premise Exchange server, please select "Exchange" from the "To" field.
- Add a Connector and name it for example "Hoxhunt Receive Connector".
- Under "What do you want to do after the connector is saved?", tick "Turn it on" and "Retain internal Exchange email headers (recommended)". Then click Next.
- Choose “By verifying that the IP address of the sending server matches one of these IP addresses that belong to your organization” and enter the following two IP addresses:
- Tick "Reject email messages if they aren't sent over TLS" to enable SSL.
- Continue by clicking Next.
- Save the connector by clicking Save.
You have now successfully configured the Receive Connector.
2. Send your MX tenant record to Hoxhunt
