There are many reasons why someone wants to forward all incoming mails from a domain to a specific address. One use case is by sure testing. If you test an application, then you probably need a lot of mail addresses. To avoid creating all the mail addresses, you could use tools like postfix for it. But it also requires some setup and configuration.
I am Office 365 user and I love it and by sure, I want to solve this issue with Office 365. I tried it and it took some time, but then I found the right setup.
So, what I want to achieve is simple:
All mails sent to @tst.axr.at should be forwarded to a shared mailbox, where all testers have access (or to specific address).
Sounds simple and you can easily configure it in Office 365, but there are a few pitfalls, that’s why I created this blog post. So let’s go through it step by step.
