Essential Questions and Answers on Mail Exchange in "INTERNET»INTERNET"
What is an MX record?
An MX record or Mail Exchange record is a type of DNS record that contains information about which mail server is responsible for receiving emails for a particular domain. It specifies the mail server hostname and associated priority value used to determine priority in delivering emails for that domain.
Why do I need an MX record?
An MX record is necessary because it informs email servers where your incoming email messages should be delivered. Without one, your emails will not reach their destination and you will not receive any incoming emails.
How does an MX record work?
When an email message is sent to your domain, its DNS lookup will reveal the MX records associated with your domain name which provide directions as to which mail server should process the messages. The DNS lookup also resolves the IP address of the mail server so that it can send the message to its correct destination.
What are different types of MX records?
There are two types of MX records - primary and backup (or secondary). Primary records handle all incoming email traffic while backup ones act as fallbacks if the primary fails or goes offline for any reason.
How many MX records can I have?
You can have up to 10 valid MX records per domain, however there is no hard limit on this number and some providers may offer more. It is important to note that only one primary MX record should be configured at any given time, while multiple backups can be used simultaneously.
How do I set up an MX Record?
Setting up an MX Record depends on where you registered your domain name and what type of webmail provider you use. Most often times, DNS settings must be updated through your registrar's control panel or by contacting their technical support team directly. If using a popular webmail service, look for specific instructions on setting up an extra/MX record within their documentation page or knowledge base articles.
Is it required for my primary and backup mail hosts to reside on different servers?
While it is best practice to configure primary and backup mail hosts on separate physical machines, when using cloud-based systems such as Google Apps or Microsoft Office 365 this isn't mandatory since they provide built-in redundancy across their infrastructure network.
Can I change my existing Mail Exchange Records?
Yes, it is possible to modify existing MX records as needed; however changes may take time due to propagation delays between DNS servers around the world.
How long does it usually take for changes in my Mail Exchange Records to take effect?
Depending on how quickly DNS changes propagate throughout networks worldwide, updates could typically range from 5 minutes up to 24 hours.
