i recently moved a client of mine to <http://www.webmail.us/>, a  
hosted email provider. previously we were using qmail, courier-imap,  
squirrelmail, qmail-admin, vpopmail, and spamassassin on gentoo  
linux. my client is happier because they are getting better  
filtering, a cleaner interface, a nicer web mail client, and real ssl  
certs. i'm happier because i can focus on solving the harder and more  
challenging problems and do not have to deal with maintaining an  
email server.
