New format iMail- some texts appear in code

[Rogbahia]

When I reopened iMail the other day, there was a new layout texts that were legible in some old and new emails appear in long code like these first few lines
:
body,table,td,p,a,li,blockquote{
-ms-text-size-adjust:100%;
-webkit-text-size-adjust:100%;
}

.ReadMsgBody{
width:100%;
}.ExternalClass {width:100%;}.ExternalClass, .ExternalClass p, .ExternalClass span, .ExternalClass font, .ExternalClass td, .ExternalClass div
{line-height: 100%;}#backgroundTable {margin:0; padding:0; width:100% !important; line-height: 100% !important; background:#FFFFFF;}img {
outline:none;
text-decoration:none;
-ms-interpolation-mode: bicubic;
}
a img {border:none;}
.image_fix {display:block;}p {
font-family: "Arial";
font-size: 13px;
line-height: 150%;
margin: 1em 0;
padding: 0;
}h1,h2,h3,h4,h5,h6{
margin:0;
padding:0;
}h1 {
color:#000000 !important;
