I have a custom domain, example.com, and I'm currently managing email services between two productivity suites. I've moved my email address ([email protected]) from suite A to suite B, but my co-workers are still using suite A ([email protected]). I want to configure the domain so that my email on B works while my colleagues remain on A. Specifically, I need help figuring out how to keep [email protected] on A while using [email protected] on B. What setup do I need for this to work?

What you're looking for is known as split delivery or split mail routing. Since your MX records can only point to one server, you'll need to route emails from one server to another for specific users. If most of your team is still using suite A, keep the MX records pointed there and set up forwarding from A to B for your address. Just remember to update your SPF records to include both servers so that your outbound emails from B won’t fail due to SPF checks. DKIM also needs to be configured properly for both servers to sign with your domain.
Totally agree! That way, everyone's mail goes to A first, and you get to manage your own email on B without hassle.
Delivering emails to two different platforms is tricky since email can only be sent to one designated server. Check if either of your platforms allows free forwarding. If not, you might need to set up a secondary domain solely for routing between the two servers, which could complicate things further. Honestly, you may want to consider unifying all users onto one platform for long-term simplicity; the savings might not be worth the trouble of keeping them separate.
I'd have to agree on the consolidation; managing two systems is not just a cost issue but also increases the risk of missing important emails.
If you're using Microsoft Exchange, you'll need to change your accepted domain from Authoritative to Relay for both systems. Although the specifics might vary depending on your setup, this type of functionality is generally supported across most mail systems.
Without knowing the specific productivity suite you're using for your MX records, I can't provide detailed guidance. However, check the knowledge base articles on configuring email co-existence; that should give you a good starting point!
Remember, typically one mail server must receive all emails. When an email arrives, that server checks if the user's mailbox exists locally—if not, it routes it to the other mail server you've set up. So, keep that flow in mind when configuring your system.
Just a heads up, handling email routing this way isn't really an issue but rather how SMTP and its infrastructure are designed to function. If you're willing to put in some effort, you could consider creating a secondary domain for forwarding messages back and forth, though that would be a bit hacky.
Exactly! It's crucial to ensure both servers are covered in the SPF record. Otherwise, you'll run into delivery issues.
