[MLB-WIRELESS] Email address format of online mail archives

[Rowan 2008]

Hi all

I recently changed my outbound email address and already I'm seeing spam. 
I have sent very few outbound emails so I suspect my address may have been 
sourced from the melbwireless mail archives available online. Is there any 
way to obfuscate the address further? It's currently displayed in 
"username at domain.com" format (eg 
http://wireless.org.au/pipermail/melbwireless/2007-September/020657.html ) 
which isn't hard for a spam crawler program to decode...

Cheers.
