[Solved] Email Regex. Is this regex expression appropriate? [duplicate]

Question

What do you think of the above expression for email validation.

For one, it doesn’t accept my address. So, there’s obviously a bug in there somewhere. I suggest you read RfC5322 carefully, it describes the valid syntax for addresses quite clearly, although unfortunately it hasn’t yet been updated for IDN.
