Questions about HTML order confirmation email

[haykgrigory]

Thanks for the quick answer lat9.

I have changed the settings to

(a) Make sure your "E-Mail Transport Method" is set appropriately for the webserver you're using. Using SMTPAUTH is strongly advised. Do not use "PHP" unless nothing else works.
(b) Use MIME HTML When Sending Emails = "true"
(c) Send E-Mails = true
(d) Email Archiving Active? = If you are testing or debugging, we recommend setting this to "true" -- note, this will increase your database size regularly.

When I did this customers would not get the email at all.

I Changed (a) back to PHP and after submitting another order i got an email that looks like the attachment.
