I've been using a catchall domain for 25+ years. Caught some companies leaking or selling my email addresses, too (the one I was most irritated with was Godaddy). Including the company's name in the salted address is usually confusing to support staff, so I just use its initials or something memorable. Some places also seem to have dirty and suspicious word filters (for instance, mail to my child's school will just silently get dropped because of my domain name, and I have to use a gmail account instead).
