If you are noticing significant delays in Outlook, you should turn off SpamCatcher Network checks. The Internet connection may be slow. If you are behind a firewall and can not access port 443 on db11.spamcatcher.net, then you need to choose one of the following options to eliminate the delays:

• We currently support HTTP or HTTPS proxies. This is the easiest solution if you already have a HTTP or a HTTPS proxy.
  
• We support the HTTP protocol via port 80. If the client can connect to port 80 of the Mailshell servers, this is an easy solution.
  
• The client does not need outbound Internet access if the Gateway product is installed. The Gateway product needs access to the Mailshell servers though.
  
• A NTLM Authorization Proxy Server can be installed:
  
  • http://apserver.sourceforge.net/
    
  • http://search.cpan.org/dist/connect-tunnel/connect-tunnel
    
  • http://download.com.com/3000-2155-10122346.html?tag=lst-0-10
    
• A port forwarder can be installed to forward to port 443 on our servers. For example:
  
  • http://portfwd.sourceforge.net/
    
• A standard HTTP proxy can be installed. Here are several free ones:

  • http://httpd.apache.org/docs/misc/FAQ.html#proxy

If you are still noticing delays in Outlook, you can, if you have a POP account, install the SpamCatcher Universal edition in addition to your SpamCatcher for Outlook edition. Performance should significantly increase if SpamCatcher Universal is configured and also running.
