Validate a comma separated email list

Question

I\'m trying to come up with a regular expression to validate a comma separated email list.

I would like to validate the complete list in the first place, then split

I agree with @crisbeto's comment but if you are sure that this is how you want to do it, you can do it by matching the following regex:

^(\s?[^\s,]+@[^\s,]+\.[^\s,]+\s?,)*(\s?[^\s,]+@[^\s,]+\.[^\s,]+)$
