In my Yahoo! email, some emails I get are HTML formatted - ok so far. But I've sent some emails to myself from various sources, and some of the emails' headers are modified to remove the extra content, leaving the header with plain text only, or utf8.
Why does this happen? Why does Yahoo! randomly strip out stuff from the header on only SOME emails? Is there some kind of filter or what?
