Documentation checklist

• Is there a changelog entry (guidelines)? If you don't add one for something awesome and new (however small) — how will our customers find out? Changelogs are automatically posted to RSS feeds, the Discord, and X.
• The documentation style guide has been adhered to.
• If a larger change - such as adding a new page- an issue has been opened in relation to any incorrect or out of date information that this PR fixes.
• Files which have changed name or location have been allocated redirects.

Minor suggestion: Since this isn't really a 3-step process, I recommend removing the steps.

Suggested change

	When onboarding a domain with MX, BCC, or Journaling:
	When onboarding a domain with MX, BCC, or Journaling, select the desired processing location (Germany, India, or Australia). The UI will display updated processing addresses to that specific region.
	For MX onboarding, if you domain is managed by Cloudflare, you can automatically update the MX records from the UI.
