My Laravel web application sends a mails to a organisation based on what the customers selects. The customer can choose out of 275 mail addresses like: email@example.com. Those mail addresses are already stored in my database and this works fine.
I optionally want to add some text to all the current 275 email address like so: firstname.lastname@example.org. But if I no longer want to send the mails to: securemailsending I should be able to turn it of for all 275 mail addresses. In that case all mails are send to test@[login to view URL]
