pop3d proxy

[Michael J Farina]

I am setting up a cyrus imap murder for a large number of accounts. In my
stress testing I have noticed that the pop3 proxy has quite a delay. When I
connect directly to a backend I can check mail at a very fast rate about .5
secs a mailbox. When I connect to the proxy the wait time increases a ton to
about 5 secs. I am thinking I must have a configuration problem. I will
include my imapd.conf and my cyrus.conf I am using cyrus 2.2.3.
