Sounds reasonable to me.  All the archive processing is done on a Unix
machine, so it's trivial to write a sed script to do the substitution 
before the archives are posted to the web.  It is also relatively
easy to process all the old archives.  I just ran a quick test and it 
appears that changing the @-sign doesn't break the hypermail links.  
That is good news.  So I will change all the old archives, and modify
my archival scripts to do this for all future archives.  I'll notify 
the list when complete.

There is a lot of spam sent to the list address, but is rejected since
only members can post.

FWIW, I'm on 7 or 8 different lists, and don't get near the spam that 
Jarrid is seeing.  I think my company is doing some filtering at the 
firewall, though.  If your mail program has built-in filtering, it can
be of great help.  A couple of well-written filter rules can zorch a 
high percentage of spam.  Also, Brightmail.com offers spam filtering
services for both ISPs and individuals.  My personal ISP, hiwaay.net,
uses Brightmail and it works VERY well.  I used to get a lot of spam
at my hiwaay account, and now get almost none.  If your ISP isn't 
using Brightmail or a similar service, ask them about it.
