CodeIgniter Email Error

I'm making use of the CodeIgniter Email class to send emails. Unfortunatel开发者_Python百科y none of the emails are getting sent - instead, I keep getting this message:

We do not authorize the use of this system to transport 
unsolicited, 220 and/or bulk e-mail.

It looks like you're using the mail or Send mail functions of PHP to send mail. Do note that these functions by default inherit the mail settings of your web hosting server (or local server), and from the looks of your error it seems that your web host does not allow sending email without some kind of verification of your application or some configuration.

This doesn't look like a generic CodeIgniter error, or an SMTP error. Check with your hosting provider, or if you're running on localhost, check your server mail settings.

Try sending mail with other smtp mail server such as gmail, etc.
