In researching about php mail and SMTP I found this citation:
PHP mail uses the settings in PHP.ini to send email through sendmail. Sendmail is a direct path that just hands over the mail you generated to the system's SMTP server, but requires you to build the header for it. PHP mail does not support SMTP authentication, which is required by many mail servers. Since SMTP requires a valid login to send the mail, the headers match the rDNS records allowing a flawless delivery.
In the long run, SMTP email is the only way to guarantee that your email will arrive in the inbox of your receivers. So don’t waste your time with the PHP mail function, instead use a web form that requires SMTP logic.
Can you please address which of the two systems work the best within abantecarte?
If one chooses SMTP what, if any changes need to be made either within the system, or within the server?
Additionally, can more than one email address be used, in either configuration? I would like to use orders@mydomain for order, newsletter@mydomain for sending newsletter etc. I have search Documentation and the board, but can't find any guidance.
If we can use more than one email address, where do we set that up?
Thank you for your response.
