I use qmail, where - has been the extension for, well, since it was created. If you're a postfix person, you can use + or -, with recipient_delimiter. You're less likely to bump into issues with -. Some shops don't like their trade name in the email, so rot13 (g? in vim) solves that if your goal is to trace back the leaks. I have not found a reliable way of auto dropping mail from bad sources, sometimes companies change name which makes it hard to validate From with recipient.

> If you're a postfix person, you can use + or -, with recipient_delimiter. Even better: postfix and dovecot (as of v2.3) now both allow specifying multiple recipient delimiters. So if you run your own mail server you can specify as many recipient delimiters and switch between them if websites are being picky.
