We didn't want webmail to kill our imap server, so we wrote a caching proxy server. If a webmail client wants to make a cajillion (I think that's a real number, by the way) connections to our server, the proxy only has to create one. We're using it, and a handful of other sites might be using it, too. If you're interested, you can grab it from: ftp://ftp.pitt.edu/users/d/g/dgm/up-imapproxy.tar.gz It's not autoconf'd, it will only build on Solaris, and it has some site-specific stuff in it.
