E-mail messages in HTML format.

With Winsock control I create E-mail messages in a plain text format. Do anyone knows how it is possible to make those mesages in HTML format with embeded images. For example something like, E-mails from www.zdnet.com.

I noticed that sometimes when I receive E-mails, those messages contain HTML tags, but they just appeared like common text messages, containing tags and thats all, no actual HTML page being displayed.

Hi,

When i was working with JMail, you had to specifiy some kind of header called content-type:

text/html or something like that gives you support for displaying HTML

The messages that you will send are simle text files with HTML tags embedded into them. Its upto the mail recieving software to correctly recognize the mail type (using the header information)and show it accordingly.

Thanks.

But I am wondering, why some of those messages are being recognized properly and the others are not?
Can it be some plugins, installed on the receivers machine?
