@heimweh could you review, please?

I'm nobody, but this seems correct to me, and would remove some clicking-hacks from our automation.

@tibibo thanks for submitting this! Unfortunately, this is an undocumented part of the PagerDuty API. I've been trying to hunt down the answer of whether there is a plan on documenting it. Once I have that I can make the decision of whether to merge this (and the subsequent feature in the Terraform provider) or not. I'll post back to this thread when I get an answer.

I was looking into this as well, and stumbled upon this PR. Any updates on this? Or is there another way to set custom rules for e-mailmanagement through Terraform?

@stmcallister as I see missing part have added in documentation —  https://developer.pagerduty.com/api-reference/reference/REST/openapiv3.json/paths/~1services~1%7Bid%7D~1integrations/post (Check tab "Email Integration With Filters"). Could you review this PR, please.
