regex help

Not the best regex king, so I need some help please

within the field "From" in my data there are emails. Within the emails there should never be a number before the @.

For example, [email protected] is not valid, but [email protected] is valid.

I want to find all the non valid emails.

If you want to get good with regex then go to www.regex101.com and put some sample data in and test it

This will find all emails with a number before the @ symbol

\w+\d@\w+\.com

index=foo ... | rex (?P<Bad_Email>\w+\d@\w+\.com)
