*rotfl* Gmail claiming localhost as a permitted sender; your editing has
given a ... "quirky" result, which makes it harder for others to help
you.

So, this isn't a spam decision being made by anything under your direct
control. It's not a knob tuned incorrectly in Exim, it's "how you are
perceived by others".
I wrote this a little while back:
http://bridge.grumpy-troll.org/2010/04/email-cooperation.html
which explains how email is about people cooperating to get messages
delivered.
When delivering to large providers, it's largely about "what reputation
do I appear to have?". One page I link to in the above article is:
http://research.google.com/pubs/author70.html
which gets you to “Sender Reputation in a Large Webmail Service”,
presented at CEAS 2006 by one of the architects of Gmail's spam
filtering system.
I suggest that you set up DKIM, so that mails sent by you can be
provably tracked back to your domain, not just to the IP addresses
you're using, so that over time you can establish an independent
reputation. That way, if you're not spamming, your mail will gradually
become less likely to be filtered as spam, even if the other users of IP
address space near you are not as trustworthy.
