I want to create a loop to reject the email addresses that start or end with an @ character, contain multiple @ characters or contain no . (dot) characters. I have a problem with the condition for contain multiple @ characters or contain no . (dot)characters. My conditions don’t run correctly. Please help me. Thank you very much.
