Users are not receiving some or any Hoxhunt emails
If there's a problem in whitelisting and mail flow rules, simulation emails from Hoxhunt may end up in Junk folder or even quarantine. This article gives few tips on how to troubleshoot the root cause.
Perform Mail Trace
Perform a Mail Trace to see if your mail flow rules were applied correctly. If you have a Hybrid environment, perform mail trace at every email server on your message path.
Check Security Filter logs
If you have additional security solutions in place on your message path, check their logs. Hoxhunt email may have been quarantined.
Also look for Hoxhunt's sender IP address in email headers. If the IP address is not one mentioned above, your Security filter may have changed the originating IP address.
Check order of Mail Flow rules
Also check the order of your mail flow rules. If you have a spam filter rule in place that has a higher priority than your Hoxhunt rule, this may prevent Hoxhunt emails from being delivered successfully.
Solution: Raise the priority of Hoxhunt mail flow rules.
Consider Partner Receive Connector
Evaluate if Hoxhunt would be allowed to send emails directly to mail server MX bypassing most filter systems. This helps to keep the messafge headers intact and mail flow rules can detect Hoxhunt email better.
