    Maybe some zimlets are trying to call port 80?
    You could install Fiddler and trace the connection.

    Maybe the sender's email signature contains some image stored on the zimbra users briefcase or something?

    "View source" might reveal what is linking to the zimbra server from that mail.

    Maybe email signature?

    You need about 50-150mb/user memory for logged in users, meaning in theory if you assume only 33% of your users are online at anytime 24Gb would be enough. 24/330 -> 73Mb

    This is usually the case, when you have consumer-grade internet.
    Yes, the corporate line costs a lot more, but you should get an IP which isn't blacklisted.

    MTA is postfix, it sends and receives mail.
    Proxy is memcached, it speeds up serving pages from your zimbra web interface server.
