A general reply to the topic: have you considered munging
addresses in a way that is still human readable, but obviously
obfuscated?

On some other project, I settled on HTML "&#8226;" as a replacement
for '.' for admins who enable that option.  The $USER@$NO_DOT
remains as-is for easy identification+recognition of hosts.

I also considered Unicode homographs which can look identical
to replacement characters, too; but rejected that idea since
it would cause grief for legitimate users who would not notice
the homograph when pasting into their mail client.

Anyways, here's the list of candidates I tried:

homograph∂80x24.org
homograph@80x24ͺorg
homograph@80x24·org
homograph@80x24•org
homograph＠80x24.org
homograph﹫80x24.org
