Please consider, we need to test email, and/or any other outbound communications, in our Dev environment.

For now, we confirmed with Squiz product team, there will be no outbound email from Dev environment, by over-writing sender address.

But, by doing this way, we can't test any Emails and/or any other outbound communications, e.g. email template.

If there is a Dev mailbox, will trap all dev emails, it will be good for thoroughly test end to end development.
