Set-up for Success: What to Do Prior to Mail Flow Cutover
This guide provides an overview of product features and related technologies. In addition, it contains recommendations on best practices, tutorials for getting started, and troubleshooting information for common situations.
Tip #1: Prepare The MX Record
- Set the TTL of your MX record down to as low as your DNS provider will allow.
Go Daddy will allow this to be set as low as 600 seconds 10 minutes.
- The results of doing this are that after making the cutover to Spambrella mail flow will take and resume in as short a period as possible.
- Make sure you have an SPF Entry that is only Spambrella or that also includes Spambrella if you have third parties that send out an email on your behalf.
- SPF for US Customers: v=spf1 a:dispatch-us.ppe-hosted.com ~all
- SPF for EU Customers: v=spf1 a:dispatch-eu.ppe-hosted.com ~all
Tip #2: Onboard Users Prior To Mail Flow Cutover
Spambrella offers several User Discovery methods. We suggest you discover users prior to mail flow cutover to ensure that we can immediately pass mail. Consider the following questions:
- Do you want to send a Welcome Email? If not, see How to Disable Welcome Emails
- Which User Discovery tool do you want to use? We recommend the following hierarchy, based on the effectiveness of each tool:
- Office 365 Active Directory Sync
- Active Directory LDAP Sync
- CSV Import
- SMTP Discovery (we suggest only using this tool as a last resort and for a limited time)
Tip #3: Verify Domain
Verify that you control the domain within the Spambrella UI. See How to Verify a Domain
Tip #4: Adding Sending Servers
Add in any and all of your sending servers under Company before you take and cut your mailflow over. This also includes turning up Managed Hosted services for either of Office 365 or Google Apps. This can be done in the UI by navigating to ‘Administration’ and clicking Account Management > Domains > New Sending Server
Tips #5: Enable Mail Relay Prior To MX Record Change
Prior to changing your MX record, take and enable relay for your domain for at least 30-60 minutes in the Spambrella Web UI. You can accomplish this by navigating to ‘Administration’ and clicking Account Management > Domains and clicking the button to the right of your domain until it is shown as green like this example:
