Prestashop: FO - Checkout / Email validation not verify mail extensions ( .fr or .com)

[SD1982]

Describe the bug

In the checkout process , the email address is not correctly verified
If @ is missing the error message is correctly displayed and we can't continue the checkout process
But the extension ( .fr or .com) is not verified and we can continue the checkout process without any mail extensions

Expected behavior

The email address should be correctly verified

Steps to Reproduce

Steps to reproduce the behavior:

1. Go to FO
2. Add products to cart
3. Start the checkout process => continue as guest or create customer
4. In the email field try to just add => demo@prestashop
5. Click on continue
6. See error => the checkout process go to the next steps => it should not

As discussed in Slack, I believe 1.7.6.9 behavior is faulty while 1.7.7.0 behavior is correct

According to https://en.wikipedia.org/wiki/Email_address the email address demo@prestashop is valid. It should not be rejected by PrestaShop.

@matks I think Prestashop mail validation rules must be compatible with swiftmailer RFC validations to avoid :

PHP Fatal error:  Uncaught exception 'Swift_RfcComplianceException' with message 'Address in mailbox given [[email protected]] does not comply with RFC 2822,

Ex.: [email protected]
| | validators | status | note |
|:----------:|-------------|:------:| ------|
| Pretashop | Validate::isEmail() | :heavy_check_mark: | Customers can register and log in
| Swiftmailer | https://github.com/egulias/EmailValidator#getting-started | ❌ | Customers cannot receive any prestashop mail

@PululuK it will be the case in 1.7.7.0 https://github.com/PrestaShop/PrestaShop/blob/1.7.7.x/classes/Validate.php#L62
