Setup of new domain aliases before DNS verification

I already have aliases setup for my own domain using another provider. To avoid interruptions to mail delivery, I would prefer to set up all aliases prior to pushing “Go”, in other words prior to reconfiguring my DNS records, at least the MX records. Documentation indicates that to even add the domain, it requires complete setup first, including MX record changes. Is there any way to delay actual email processing–allowing email to flow through existing mail services–until my custom domain is properly setup on SimpleLogin?

Hi one solution is to enable the catch-all as soon as the MX records are verified on SL. This way SL will automatically create an alias if it doesn’t exist for incoming emails.

There can be a short time between the MX record verification and when the catch-all is turned on where emails are in the limbo state but this is often less than a couple of minutes.
