00:00:00.000 --> 00:00:06.000
How does a sender find the mail service for your domain?

00:00:06.000 --> 00:00:13.000
MX records identify mail-server destinations for incoming email.

00:00:13.000 --> 00:00:18.000
Check the mail route before changing DNS.
6 MX-record basics.

00:00:18.000 --> 00:00:30.000
MX means mail exchange
The record helps route messages towards the domain mail service.
Recipient domain · Mail exchange record · Incoming mail route

00:00:30.000 --> 00:00:42.000
The value names a mail server
Use the destination supplied by the business email provider.
Provider hostname · Mail destination · Exact supplied value

00:00:42.000 --> 00:00:54.000
Priority controls preference
A lower preference number is tried ahead of a higher number.
Preference number · Preferred destination · Alternative destination

00:00:54.000 --> 00:01:06.000
Website hosting is separate
Moving the website does not necessarily mean moving the mailbox service.
Website host · Business mail provider · Separate services

00:01:06.000 --> 00:01:18.000
Authentication has another role
SPF, DKIM and DMARC concern authentication alongside the mail route.
Incoming route · Sender authentication · Related DNS settings

00:01:18.000 --> 00:01:30.000
Test real incoming delivery
After a planned change, confirm mail reaches the intended mailbox.
External test message · Correct mailbox · Provider delivery evidence

00:01:30.000 --> 00:01:39.000
Your checklist
MX means mail exchange · The value names a mail server · Priority controls preference · Website hosting is separate · Authentication has another role · Test real incoming delivery

00:01:39.000 --> 00:01:47.000
Keep incoming email in the DNS migration plan.
