In the Zen-Cart Email Options the first option is called "Email Transport Method". Which option works best with Dreamhost servers? I'm on a Linux/Unix server but should I choose sendmail, sendmail-f, or Qmail?
Or should I just use the default: SMTP? Here is the information provided by Zen-cart:
Zen-Cart Wrote:E-Mail Transport Method
Defines the method for sending mail.
PHP is the default, and uses built-in PHP wrappers for processing.
Servers running on Windows and MacOS should change this setting to SMTP.
SMTPAUTH should only be used if your server requires SMTP authorization to send messages. You must also configure your SMTPAUTH settings in the appropriate fields in this admin section.
sendmail is for linux/unix hosts using the sendmail program on the server
"sendmail-f" is only for servers which require the use of the -f parameter to send mail. This is a security setting often used to prevent spoofing. Will cause errors if your host mailserver is not configured to use it.
Qmail is used for linux/unix hosts running Qmail as sendmail wrapper at /var/qmail/bin/sendmail.
