Encoding your email address using Character Entities.

For example:
On your webpage you have the following text:

"For more information, send email to uniqueid@muohio.edu."

The HTML for the webpage, the above would be encoded and presented as follows:

"For more information, send email to <A HREF="mailto:
&#117;&#110;&#105;&#113;&#117;&#101;&#105;&#100;&#064;
&#109;&#117;&#111;&#104;&#105;&#111;&#046;&#101;&#100;&#117;">
&#117;&#110;&#105;&#113;&#117;&#101;&#105;&#100;&#064;
&#109;&#117;&#111;&#104;&#105;&#111;&#046;&#101;&#100;&#117;
</A>"

You can see this by typing in the same email address as above in the form below, which will encode the address and produce the following:
&#117;&#110;&#105;&#113;&#117;&#101;&#105;&#100;&#064;
&#109;&#117;&#111;&#104;&#105;&#111;&#046;&#101;&#100;&#117;
