can I send an email without SMTP on the current codeigniter version?
what I'm trying right now is to send an email with Gmail's SMTP and succeed. however, when I did not set the configuration of the email library, the email was not sent even though there was no error message. whereas, in version 2.x it can send emails even without configuring the email library. can anyone help me solve this? or can anyone give me information about the email library in Codeigniter 3, is there really a change from the email library in version 2.x? Thank you in advance...
