MX Record

MX stands for mail exchange. An MX Record is a record in DNS that specifies the address of the mail server receiving emails for a particular domain. A single domain can have multiple MX Records specifying several mail servers. When a domain has more than one MX Record, emails will attempt to be delivered to each server in the order that they are listed. An example of an MX Record for a domain hosted on the IT-100 is:

mail.domain.com resolves to 192.168.1.45 (this IT-100). See the Glossary entry for DNS for more information.
