Problem:
You have a sender that needs to send a large volume of email and is likely to hit the bulk-rate limits set by proofpoint.
Solution:
Use a bypass rule & connector to bypass proofpoint altogether for that specific use-case
Summary:
You need both a connector and a corresponding rule that calls said connector
Connector
Name: "Bypass proofpoint"
From O365
To Partner Organisation
If invoked by a mail flow rule
Use MX resolution
RULE
If sender is (your specific user that needs to send direct)
and recipient is outside your organisation
and (other condition) then
route email using "Bypass proofpoint" connector
Example:
IMPORTANT: Make sure you have office365 in your SPF record.
include:spf.protection.outlook.com needs to be in there (in addition to whatever else you may have)
Create the bypass Connector
Create the conditional rule that will call this connector
