I have a large list of emails I am running through. A lot of the emails have typos. I am trying to build a string that will check valid emails.
this is what I have for regex.
def is_a_valid_email?(email) (email =~ /^(([A-Za-z0-9]*\.+*_+)|([A-Za-z0-9]+\-+)|([A-Za-z0-9]+\+)|([A-Za-z0-9]+\+))*[A-Za-z0-9]+@{1}((\w+\-+)|(\w+\.))*\w{1,63}\.[a-zA-Z]{2,4}$/i) end It passes if an email as underscores and only one period. I have a lot of emails that have more then one periods in the name itself. How do I check that in regex.
[email protected] # <~~ valid foo.bar#gmail.co.uk # <~~~ not valid [email protected] # <~~~valid [email protected] # <~~ not valid get_at_m.e@gmail #<~~ valid Can someone help me rewrite my regex ?

Every email ID has three components: @ symbol, a prefix, and domain. The prefix appears to the left of the @ symbol, and the domain name is to the right of the symbol. Having an @ symbol is a must for an email ID to be valid.
