Can we see the exact message you got?
Also, since you bring up the subject. I've been having issues with my mail server (self-inflicted). I'm looking to boost the spam destruction capabilities of my mail server. Seeing as how I recently discovered I'm getting slammed with 5000+ emails a day, 95% of which are thrown away at SMTP time. My server and client combination currently blocks about 98% of the spam. I'd like to bump that number up to 99.999% (hey it's a journey not a destination). I'm looking at greylisting, and also I added sa-exim to my system, but screwed up placement/context of the configuration lines and created a loop. So I've had to sdsiable my new feature which was working quite well, by blocking 100% of the spam and let through all except 1 of the emails that should have gone through. The one caused a loop in the system. So my question is does anyone use greylisting with debian and exim? I've found one sample configuration which I'm studying. But it's a bit overkill for my needs.
So, Jon send us more detailed information on your blocked ip message. I know others are using gmail on the list so it's got to be something else.

I was getting 5-10 spams a day and some other employees were getting 50-100.
I setup greylisting and now i recieve 0, and only a few users are still getting spam. Which i believe is real stuff they probably signed up for.
Greylisting has kept mine 100% spam free for the last 8 months.

I don't know exim very well, and instead have always preferred postfix. There is very useful greylisting+postfix information at http://isg.ee.ethz.ch/tools/postgrey/

<summary>suggestions on exim + anti-spam</summary>
I use Postfix + RBLs + postfix-gld + amavisd-new + spamassassin + ClamAV on the KCLUG, and my personal server. The combination seems to be as good as anything out there. The only times spam has gotten through has been when the spammer went through an ISPs SMTP server, and Spamassassin didn't score it higher than my current threshold score.

Evidently, one or two of GMail and Hotmail's SMTP servers are on SORBS[1], which we use to block open relays. It has been very effective, and this as been the only time I've ever seen a problem with it. I have a solution, but am waiting for a few free minutes to implement.

I'm already running spamassassin as I've said in the other message.
