How to Turn off outgoing email in Production?

Hello everyone,

is it possible to block all outgoing emails during Development & testing phases by a simple way in a NetSuite Production environment?

When I compare email preferences, in SB there a checkbox "Do not send email" and not in production

And the rational reasons for having this option available in SB but not in Prod escape me.

And it seems I'm not the first person to have this question when looking at another forum for example but I don't find a clear answer.

And to be honest, removing and importing again entity emails is not the ideal solution..

And we do have a sandbox account but we are making so diverse test and granular customizations and I would prefer to be able to work at one place for now and refresh SB when we will be more advanced in the implementation process. But that's another reply
