Fastmail has an even nicer feature: subdomain addressing. If you are [email protected], you can set up Fastmail to accept subdomains

[email protected]

[email protected]

Avoids catchalls ;).

Tyvm! That looks epic. Link: https://www.fastmail.com/help/receive/addressing.html Might be tricky if the time came to migrate away from FastMail though.

Indeed! This is why I stopped using it. I love Fastmail, but who knows if I feel that way in 5 years. The entire point of Fastmail + own domain is never being locked in again. Using subdomain addressing locks you in once again.

I'm with @rb666; Don't rely on it as most will support plus+ addressing but not the the fast mail subdomain addressing as I am now in the process of migrating to Migadu.com and I need to go and unsubscribe and resub using the plus+tag. It's a PITA... lesson learned, stick with best industry practices even if there is an easier method because you'll thank yourself later.

Is also nicer than plus-notation like [email protected], which from time to time gets rejected by some overly zealous (but wrong) adress checking tool.

catchalls are great. In addition to allowing the use of arbitrary custom addresses on a whim they make it really easy to identify spam and train spam filters. Anything that arrives on multiple random/unused addresses at your domain is spam.

I do this too but sometimes companies reject my replies because the from address isn't the same address they have on record. Maybe there's a way to make the "reply's from" the same as the "original's to" but idk.

With FastMail, you can select your wildcard as your "from" address on their web app, and just directly edit the `*` to be `<whatever>` and it will work fine :)

FastMail lets you change the from: address on the fly if you’ve set up a catch all.

And if you are not with fadtmail, there’s are several “multiple identities” add-ons for thunderbird (and recently a built in one, though it is still buggy) which let you add from addresses on the fly.
