i just put together a little hack that will let people use
squirrelmail on
a virtual host system from a single copy.
its php based with flat file database. its far faster than
openwebmail,
especially for those with more limited resources. it has a ton of
very
cool plugins like spam killers, and stuff. its the standard webmail
included in red hat and apple's server edition operating systems.
i have it running for all my clients already, and am almost production
ready to switch em all to the virtual copy.
more info can be found at squirrelmail.org
