FastMail Catchall/Wildcard Aliases
Can someone explain how to create and use wildcard aliases or verify what I describe here? I did some experimenting and I think either I'm doing it wrong, missing something in the setup, or thinking there's more "power" in these than I am giving them credit for.
Here's how I created a wildcard alias in the settings (actual names and domains changed for the example here):
Now here is where my confusion starts. Assuming I set up the wildcard alias correctly (did I?) what if someone knows my email address by the fake address example@123mail.org and they try to send to it? This is not a reply just some place using that fake email address. That's where I'm confused because obviously that isn't going to work. A mail sent by me using example@123mail.org has the true reply-to specified from the identity, i.e., the original myAlias@123mail.org alias and identity. So a reply has a valid place to be sent. But just the sender using the example@123mail.org as recipient address that isn't a reply has no valid place to go and will bounce. That's the reason for this post. Am I giving too much credit to the power of wildcard aliases or did I make a wrong turn in setting these things up in the first place? The intent was to supply different @123mail.org addresses to different places I need to register or specify an email address so I could tell when those places distributed it and who distributed it when they attempt to send me email using the fake address. That's what I thought was implied in the FastMail Catchall/Wildcard Alias article (more about that article later). If I am not doing anything wrong then I see no advantage to wildcard aliases and might as well just use a single distinct alias/identities and filter on those email addresses. I was hoping the wildcard alias would mean I don't have to do that. So, bottom line, I hope I'm doing something wrong creating the wildcard alias. If so, what is it? Back to that FastMail Catchall/Wildcard Alias article. It's instructions for creating an wildcard alias are either out of date or wrong. They say,

And you will want to use the identity "*@email.domain" so that when you reply to an email "you@email.domain", the FROM address will automatically update.

Ah, so there's the piece of info I was missing (or overlooking), i.e., having your own domain. I don't. Thanks for clearing that up.
