Can you have multiple mx records in a single domain
How to add multiple ip addresses for one dns a record in
Email messages are routed through the Internet using Mail Exchange (MX) records. An MX preference specifies the MX server to be used in an MX record. The values for MX preference range from 0 to 65536. A specific MX preference number is contained in each MX record. An MX record’s MX choice and TTL values can be customized.
A mail transfer agent sends a DNS question to the domain name’s MX record when an email message is sent over the Internet. This question returns a list of host names for the domain’s mail exchange servers, as well as a preference number. If no MX records are identified, a request is made for the domain’s Address record. Multiple mail exchange servers may exist for a single domain.

Depending about what you want to happen with specific emails, you can set up your MX records in a variety of ways. You may have multiple MX records for a single domain, for example, to provide continuity to ensure that emails are delivered. Some email providers can assign multiple MX records/servers to accept your email, and you can then assign a priority score to each of them. The highest priority will be given to servers with lower MX record numbers. When a domain receives a message, the MX record/server with the lowest number will be used first. Let’s say the providers use the numbers 0, 5, and 10 as examples. The MX record with the number 0 will be used first, and if that mail server is unavailable, it will switch to MX 5, and if that mail server is also unavailable, it will switch to MX 10.

The Sender Policy Framework (SPF) is an email authentication protocol used by mail servers. SPF records, which are TXT style records, are used to execute it. We discussed this idea in depth earlier in “SPF Records Explained.” We’ll discuss practical issues and how to prevent common SPF problems in this post. Setting up multiple SPF records for a single domain would be the subject of the second most common mistake.
Multiple SPF records for your domain would be rejected by the recipient server in operation, so what’s the point of making multiple entries? In certain cases, DNS TXT record replication is unintentional. As an example, consider the following:
A new email service provider, such as Mailgun, requests that you build an SPF record. You forget you already have a working Gmail account and build a new one. Finally, you should have two SPF entries:
SPF Record Check examines the SPF record in great detail. Simply type your domain name or IP address into the box and press the button. Other details such as MX records, DNS, sender credibility, and much more can be verified.

Currently, I’m using a domain name ( XYZ.com ) that points its MX to the Yahoo Business email server, which has around 300 mailboxes. We are now preparing to migrate a small number of users to Office 365. Is it possible to get the emails of a few users on O365 and leave the others alone? Note: I was also the office 365 person with the email address [email protected]
This is possible (some users on a different system); however, it would not and could not be done for MX data.
You’d have to set up forwarding in Yahoo for the accounts you want to pass at the very least. The accounts will be forwarded to the “onmicrosoft.com” address. The trick would be in how some users send out email. The solution is slipping my mind right now.
MX records don’t work like that. An MX record specifies which servers can receive email for a specified DNS domain. Multiple servers may be specified: the mail is sent to the highest priority MX server first, then the second highest, and so on. The idea was that if a higher priority server was unavailable, the client might send the message to the other server, which would then send it to the higher priority server. This was a very useful function when SMTP was invented, since the Internet back then was a little shaky. No, multiple MX records can not accomplish this. Why not take a hybrid approach when migrating to Office 365? https://support.office.com/en-us/article/59616fab-acdb-40-office-365-hybrid-cloud-solutions-overview-59616fab-acdb-40-office-365-hybrid-cloud-solutions-overview-59616fab-acdb-40-office-365-hybrid-cloud-
