Recently I was trying to send HTML based emails from a server-side script. The configuration of the server, however, wouldn’t let me send them without a bunch of trial and error or they would send and never look like I intended. A Google search on the topic returned lots of somewhat useful information with the exception of this little utility from PHPGuru. HTML Mime Mail allows you to send to multiple recipients and even send attachments.
After some working with the script I realized that the script won’t allow you to send multiple emails to the same recipient. This can cause some headaches if you are trying to test the bcc functionality. So if you’re looking for an easy way to send HTML emails from a server I would suggest looking at HTML Mime Mail from PHPGuru
