I've just had a very frustrating day trying to work out why my 1.3.6 Zen Cart website wasn't sending out all of the order confirmation emails. (i.e. I have set up the email options to send the order confirmations to [email protected], [email protected], [email protected]).
Using either PHP or Sendmail as the email transport doesn't work - it will send an email to the first address in the list, but that's it. A knock on effect of this is that if you're using the standard Credit Card payment option, it doesn't send the 'middle digits' email either.
The solution I found eventually, was to use SMTP (SMTPAuth to be precise) as the transport system.
I don't know if this is quirk of the host server or an issue with Zen itself but I just thought it might save someone else a lot of head scratching.
