Default [Q] no HTML e-mail from XDA using the stock mail client?

Just noticed this. For e-mails from XDA the e-mails are not html formatted (or don't show as such) so I can't click links etc. This is on the stock e-mail client. For other sites html is fine and XDA e-mails are in HTML format on all my other Android devices including a Galaxy Nexus, Motorola Xoom and Asus Transformer TF700.

Other people seeing this?
