    Don't do that, it breaks many assumptions, MIME, crypto signatures, and
    it's plain ugly. Adding a X-Header is a) sanctioned by the standards, b)
    robust. Take care your header is pure US-ASCII (no characters with high
    bit set), use RFC-2047 if you need to transport accents or national
    characters or something, like:

    X-Advertise-Junk: Your own mail domain
            for just =?ISO-8859-15?Q?1=2C99_=A4?= per month

    (The ugly word in the middle displays as "1,99 ¤")
