Blank HTML messages sent to Yahoo! users (and even Gmail or Hotmail users)

Hi -

Our site is running into an issue with mailing lists. We send e-mails to folks who sign up for our newsletter; first, a welcome message, then an HTML newsletter with graphics. If they want to unsubscribe, we send them a confirmation message.

Our dev team wrote the code on an Apache box running Windows. Everything worked fine - all the e-mails are successfully sent to Yahoo!, GMail, and Hotmail users and are visible in their HTML beauty.

Our production box is running IIS/Windows, however. For some reason, all messages sent to Yahoo! users are blank (subject line in tact, however). Some e-mails make it to the Gmail and Hotmail users - except the unsubscription confirmation.

The weird thing is that the unsubscription and registration files are exactly the same - just some free text in an HTML document that we mail out to users. Why one would work, while the other one doesn't, strikes me as odd.

Even more so, why everything works on Apache but breaks on IIS is also weird.

We saw the posts at:

but no luck so far. Can someone help us?
