Answer 1

You must check few things (Gmail SMTP)

1. Verify Email and Password are correct.

2. Enable Less Secure App Here

3. Enable Display Unlock Captcha here

4. Use Host: smtp.gmail.com

5. Use Port: 587 or 465 as per SSL or TLS setting

Also check newline as per below

$config['newline'] = "\r\n";

Answer 2

Please try to use below configuration in CI and make sure it's correct.

$config['protocol'] = 'smtp';
$config['smtp_host'] = 'ssl://smtp.gmail.com';
$config['smtp_user'] = 'apple@gmail.com';
$config['smtp_pass'] = 'password';
$config['smtp_port'] = '465';
$config['mailtype'] = 'html';
$config['starttls'] = false;
$config['charset'] = 'utf-8';
$config['wordwrap'] = TRUE;
$config['smtp_timeout']='30';
$config['newline']="\r\n";

Also, please ensure that gmail is allowed to access by another app.

There are 2 steps to check in gmail account.

1. Allow less secure app access. https://myaccount.google.com/lesssecureapps
2. Allow access to your Google account. https://accounts.google.com/b/0/DisplayUnlockCaptcha
