In relation to an earlier question I\'m looking for an alternative way to send an order from my website to the division in my company that processes the order.
Currently
There is inherent insecurity in using SMTP to transmit orders. Not to mention the delays caused by all the routing, spam-checking, etc. that is caused by using the mail server. Are you sure you need to email the order? Wouldn't something more along the lines of a server-to-server HTTP transfer, perhaps XML-based, be a better option?
You could use a second server in the processing division that would receive the order from your web server via a protected (firewalled) connection that would process the order, in this case making it available to the person in the order processing division who reads and deals with the order.
