This topic has been discussed in the past, with some bringing up
the issue that images would prevent those with disabilities (i.e.
vision impaired) to use it (this may be a legal issue for some
entities, not sure how accessibility affects web sites in general).

Note, mail-archive.com uses a POST form to return a mailto link
to facilitate reply capability.  This appears to be sufficient
to defeat address harvesters, but it they wise-up...

Regardless, an idea I had was to create an MD5 hash of the address,
and use that as the key to lookup the original address (via a
CGI program).  For example:


Of course, the hash is stored in some database that maps MD5
hash to real address.

I'm not sure re-rendering the page with the real addresses are

Are you trying to do this for all email addresses that appear in a
message, or just for the "from" address?
