iFrames rejected by Deutsche Telecom
I had a simple email to Germany rejected by Deutsche Telecom because of iFrames in HTML section. See part of our email exchange and part of HTML section copied below. I use AOL, but I believe the iFrame is placed by Mozilla. I don't understand any of this but I believe it may be important for Mozilla to be aware of and possibly work with Deutsche Telecom on a fix.

We found iframes in the HTML part of your e-mail. Such elements are rejected by our system in general.
