When setting up an online store (or any site that accepts payments) it's important that the end user be completely confident in the security of your website. The best way to do this is to buy and install an SSL Certificate to encrypt the transactions between your web server and your clients browser.

If you plan on using a SSL Certificate on your website, your hosting provider will require you to pay for a dedicated IP address. Without it your certificate will simply not work.

This is due to the way that HTTP Request Headers and SSL work.

If you use Google Apps for your domain, sometimes you have a "group" setup, such as  This e-mail address is being protected from spambots. You need JavaScript enabled to view it .

Mail sent to This e-mail address is being protected from spambots. You need JavaScript enabled to view it is then forwarded to the members of the group, such as  This e-mail address is being protected from spambots. You need JavaScript enabled to view it .

The problem is that when you want to send an email from the info account, Gmail adds the "Sender" header which makes it appear to the recipient as:
"From: This e-mail address is being protected from spambots. You need JavaScript enabled to view it  on behalf of This e-mail address is being protected from spambots. You need JavaScript enabled to view it ".
