greylisting and gmail

Note: This is an old post in a blog with a lot of posts over a long span of time. The world has changed, technologies have changed, and I've changed. It's likely this is out of date, the code doesn't work, the ideas haven't aged well, or the ideas were terrible to begin with. Let me know if you think this is something that needs updating.

I have greylistd installed (on Debian with exim) and noticed last monday (March 6th) that Google has something like 26 outgoing SMTP servers for gmail. That doesn't work well with greylistd, though. So I added "64.233" to the whitehosts list. Not sure if that's the right thing to do or not, though. I'm not wildly excited about adding items to the whitehosts list.
