A common concern when switching hosts is what to do about email. Any steps that may need to be taken will be dictated by where your email is hosted.
This post provides instructions for the three most common scenarios.
If your email is currently hosted with your domain registrar:
If your DNS and/or email are currently provided by your domain registrar, you should be able to update just your A (or “@”) record to point the domain to your new Synthesis IP address, which is located in your Synthesis customer portal.
If your email is hosted through a 3rd Party (example: Google Apps):
You will need to make sure that the MX records, as well as any other records that your 3rd party email service requires, are implemented in your DNS.
If you are moving your DNS control from the current provider back to your domain registrar (or a premium DNS provider) you will need to move these records.
Note that in most cases, if you are not moving where your DNS is controlled, you will not need to make any changes aside from the A record.
If your email is hosted with your current web hosting provider:
If your DNS and/or email are configured through your current hosting provider, you will need to sign up for a new email service and re-point your DNS to your domain registrar or a premium DNS provider.
