iFrame Tag in the content

[susheel]

I have placed an iFrame tag in the content and i am not able to get the same iFrame when i publish the same content in a mail. May i know weather the iFrame tag will be ignored by the major ISP's???

Most email clients will completely ignore HTML altogether, or, even if they can read HTML will have the default setting not to read it (security).

I suspect iframe is something they will ignore altogether (A huge secrity risk, as you could be calling a page that installs a trojan).
