As at the time of writing, 22/03/2023, it appears that Gandi now allow a pure wildcard to be used in an email alias, so the information below is now obsolete. You can set an alias like:

*@example.com

and point it at your desired address.

Catchall email addresses are a nice thing to have, because you can give out customised email addresses to each company you do business with, and if you start to receive spam addressed to that address you can block it without affecting your normal email traffic.

Unfortunately, my domain registrar, Gandi.net, don’t provide such a facility. They allow 1000 email redirections, but these would have to be set up in advance, which would be a pain. However, there’s a sort of work around which will give almost the same functionality as a true wildcard redirection, as follows.

Along with 1000 email redirections, Gandi give you unlimited email aliases, which is what you can use to get the catchall effect. The slight problem is that they only allow a wildcard in the alias after the first two characters. So, if we limit ourselves to email addresses where the username only contains numbers and letters, we need to create 36 X 36 usernames of the form xy*@yourdomain.com, plus 36 usernames with just a single character, for a grand total of 1332 email aliases.

If you fancy doing this, here’s the list of aliases that you can copy and paste into the appropriate section of Gandi’s email setup pages.
