What is the use of MX records?
A mail exchanger record (MX record) specifies the mail server responsible for accepting email messages on behalf of a domain name. It is a resource record in the Domain Name System (DNS). It is possible to configure several MX records, typically pointing to an array of mail servers for load balancing and redundancy.
How many MX records can a domain have?
Yes, it’s possible to have more than one MX record for one domain. Moreover, it is possible to assign priorities to them.
How do multiple MX records work?

Two MX records with the same priority will share the workload. The server with the higher preference number will be contacted only if the servers with lower preference number are unavailable (this is typically used for backup mail servers).
What is MX Gateway?
MX gateways are typically used to connect ATAs, PBXs or key systems to the converged IP network. For example, a legacy PBX may be replaced by a Cisco Call Manager. The user’s investment in voice stations can be protected by placing an MX gateway in each branch office, as shown in the figure below.
What happens when a domain has two different A records?

Can a domain have multiple mail servers?
Yes, it’s possible. You’d basically have all email delivered to your main email server – the one that’s going to host most of the mailboxes.
What does priority mean in MX records?
The priority is used to determine which MX server to connect to first, in order to get to your inbox. If there are multiple addresses with the same priority, it simply connects to one at random. You can also change your MX records from the existing one if you deem it necessary.
What is split domain routing?
1. Split-Domain-Routing is a feature that splits your domain among two different mail servers, while existing on both at the same time. The e-mail comes to AppRiver via MX records from the Internet and is routed to the Hosted Exchange server to see if the recipient exists there.
