This will parse an email like "hello@mail.com>" as valid, but if capture group 1 is used all should be OK regardless. Alternatively, the email part could be copy and pasted to split the regex into two cases, one with the 'bare' email and one with the name part in front and the email surrounded by angled brackets, but for my current purposes I'm only using whatever is in group 1 and thus don't care. Regex in a lookbehind won't work for most regex engines and I can't think of another way off the top of my head.
