An advance gentle warning to people moving to Fastmail: never use the email address on their domain “fastmail.<tld>. Just don’t. Pretend it doesn’t exist.

I regret using it on mailbox.org and I have used it at so many places in last many years that moving away seems tedious and I give up on it even before I start.
