css overlapping

I am building a mail account (Inbox) which is sung css.now there is a specific mail which contains some css elements like

<div>Dear all,</div> <div>&nbsp;</div> <div>wish u happy and safe diwali</div> <div>&nbsp;</div> <div>luv</div> <div>Vinoth<BR><BR><B><I>Palanivel_J@Dell.com</I></B> wrote:</div> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid"> <META content="MSHTML 6.00.2900.2963" name=GENERATOR> <STYLE>v\:* { BEHAVIOR: url(#default#VML) } o\:* { BEHAVIOR: url(#default#VML) } w\:* { BEHAVIOR: url(#default#VML) } .shape { BEHAVIOR: url(#default#VML) } </STYLE> <STYLE>@page Section1 {size: 8.5in 11.0in; margin: 1.0in 1.25in 1.0in 1.25in; } P.MsoNormal { FONT-SIZE: 12pt; MARGIN: 0in 0in 0pt; FONT-FAMILY: "Times New Roman" } LI.MsoNormal { FONT-SIZE: 12pt; MARGIN: 0in 0in 0pt; FONT-FAMILY: "Times New Roman" } DIV.MsoNormal { FONT-SIZE: 12pt; MARGIN: 0in 0in 0pt; FONT-FAMILY: "Times New Roman" } A:link { COLOR: blue; TEXT-DECORATION: underline } SPAN.MsoHyperlink { COLOR: blue; TEXT-DECORATION:
underline } A:visited { COLOR: purple; TEXT-DECORATION: underline } SPAN.MsoHyperlinkFollowed {


when this mail is opened,its css interfers with the css of the page.
as a result links all over the page are colored in blue.
what is the method to avoid or ignore any css of the mail.
