Generate Dynamic Email Havesting Blocking Code

[Newsgroup_User]

Is there any way out there to encode email addresses dynamically to prevent
email harvesting?

My employer would like to to populate a list of employees with their email
addresses dynamically and encrypt them so they cannot be harvested.

Any ideas how?

That is sharp, but I need to display the persons name and link it to the
email address.
The same as this:
<a href="mailto:me@me.com">me< /a>
Can that be done with this?

[murpg]

Of course it can. Just do this. <cfoutput><a href="mailto:#EmailAntiSpam("me@me.com")#">me< /a></cfoutput>

The script needs to be at the top of the document or above the cfoutput block.

Thanks a ton. Worked like a charm!
