In some email systems like postfix, you can change what the + character is (like . or _ or even numbers) So you could have username_football@example.com

- chmike 16y agoUnderscore is not a valid character in user names. Use - instead.
- mike-cardwell 16y agoYou're confusing "usernames" and "email addresses". Underscores are fine in the local part of an email address. The following are also valid: O'Reilly@example.com "Foo@Bar"@example.com
