I have been using a catch-all on my domain for e-mail so I can sign up for site with addresses like email@example.com. Now, the catch-all is not an ideal solution since it also catches all of the spam sent to bogus addresses. Is it possible to setup a forward with a wildcard in the address? For example, could I forward firstname.lastname@example.org?
No, but wildcards are on the suggestion list as:
2005-05-16 Mail - Addresses Allow “semi-catch-all” emails like “email@example.com”.
