Install the SPT app & forward local ports 1043, 1125, and 3128 to remote 
143 (imap), 25 (smtp), 3128 (squid proxy).

In my case, SPT Forwards = 

Here, is the internal address of my server (not its external 

The forwarded local ports need to be > 1024, IIRC.

You point the email client at localhost for the SMTP/IMAP, using the 
special local forwarding ports 1043 and 1125.

For web use, I use Firefox, and in about:config set:

network.proxy.type = 2
network.proxy.autoconfig_url = http://www.avtechpulse.com/proxy/avtech.pac

That *.pac file says:

function FindProxyForURL(url, host) {
	if (shExpMatch(host, "*.domain.avtechpulse.com"))
		return "PROXY";

  	return "DIRECT";

That means squid serves the private intranet pages from the private 
squid server, and firefox accesses all other pages in the normal manner 
(not through squid).

Firefox is the only browser that handles this proxy trickery well.

Sounds complicated, but works like a charm.
