Question : Exchange 2007, how to configure exchange anti-spam to always pass content filtering for several external mail domains

Hi,

In our w2k3 domain, we use exchange 2007 as mail server.
In the dmz zone, we have an edge transport server.
On both servers, exchange anti-spam is enabled. On the mail server, forefront for exchange is also installed.

Now, my problem is that several mails from external companies, with attachments included, are blocked by exchange ant-spam.
Most of the attachments are zip files with .cmd and .sql files included, so i think it's normal that these mails are blocked, but how can i configure exchange transport server and/or exchange 2007 mail server, to not check the content from several domains?

Another problem is that we still receive a lot of spam, ...

thx

Answer : Exchange 2007, how to configure exchange anti-spam to always pass content filtering for several external mail domains

Hi While1-Breathe,
The issue results because of the IE ClearType rendering and there are actually many fixes for it apart from the one in the link you provided.

The issue results from specifying a width & opacity filter for the same element, while if the width was specified for a parent element it won't happen.

Also Arial font is the worst case, while if you use Tahoma for example it would look a lot better though it's still not using the fix

Finally applying the background should work even for <li> elements but if you specify the background color to an upper level than the one having the opacity applied to it won't work, for example if you have an <li> with a class where filter is applied, setting the background for the <ul> won't fix it, but the opposite would.

Try the below example, it should show you many cases and check which one would work best for you.

Cheers

<div style="font:normal 14px Arial, Helvetica, Serif;">
        <div style="background-color:#fff">
            <ul style="width:100%;filter:alpha(opacity=90);font-weight:bold;">
                <li>This is not working</li>
            </ul>
        </div>
        <div style="width:100%;filter:alpha(opacity=90);font-weight:bold;">
            <ul style="background-color:#fff">
                <li>This is working!</li>
            </ul>

        <div>
            <ul style="width:100%;">
                <li style="filter:alpha(opacity=90);font-weight:bold;">This is working too with no fix required since no width is specified for the element but instead it's specified for the UL</li>
                <li style="filter:alpha(opacity=90);font-weight:bold;width:100%">while this doesn't although they're both &lt;li&gt; elements but this one has a width specified</li>
                <li style="filter:alpha(opacity=90);font-weight:bold;font-family:Tahoma;">Tahoma Font Working</li>
                <li style="filter:alpha(opacity=90);font-weight:bold;font-family:Tahoma;width:100%">Tahoma Font not Working which still looks much better than Arial</li>
            </ul>
