Hello,

I'm running spam blocker and it seems to be doing a good job filtering out spam... I've gone from about 200 per day down to less than 10 (knock on wood).

One problem:
Code: 
2008-02-06 14:30:23 H=smtp.cogeco.net (fep1.cogeco.net) [216.221.81.25] F=<[email protected]> rejected RCPT <[email protected]>: Email blocked by SPAMCANNIBAL - to unblock see http://www.example.com/

I don't know why but this sender has reported that it was sent back due to spam. Can someone tell me A. why this is happening and B. how do I allow it?

Thanks
 
The sending server is blocked at spamcannibal you would have to go to their website to get it removed.

You can also add either the users email address to /etc/virtual/whitelist_senders

or the sending servers hostname to /etc/virtual/whitelist_hosts

But that method really isnt recommended due to the potential abuse from those addresses.
 
Comment out spamcannibal in your /etc/exim.conf. That RBL is WAY too aggressive. It blocks one too many legit domains for my taste.
 
It's one reason I'm moving away from SpamBlocker.

The process is flawed...as you're relying on 3rd parties (RBLs) for access via SMTP.
It really comes down to how they 'deem' the sender.. if good or bad. This also means it's likely to get false positives from time-to-time.

What will you use instead?
 
Definitely remove SpamCannibal. I'll try to get a release candidate out within the next week, with more up-to-date blocklists.

I've commented out SpamCannibal. Hopefully, I won't start getting a whole bunch more spam now. SpamBlocker overall has been doing a pretty good job. It has cut my spam down from about 200 per day to about 10 or 15.

I don't know how they do it but RIM has it down perfect. I have NEVER received any spam on my blackberry and it is set to forward every single email I get.

Does anyone know how to get this setup like that?
 
Indeed, SpamCannibal is not usefull. Jeff: will you make an exim.conf RC for Dovecot users too, like you did with Spamblocker 3?
 
A customer of mine couldn't receive emails from someone. Turned out that spamcannibal had the IP blocked. No other rbl's I checked had the IP blocked. I commented out spamcannibal as it doesn't seem like a very good source.
 
We now only support SpamBlocker 3.1-beta and later. Unfortunate, but the others just don't cut it anymore :(. We strongly suggest updating, first to Dovecot (which is required), and then to the latest version of SpamBlocker.

Yes, we've removed SpamCannibal, and also most of the domain-based comparison tests (except for PayPal). And added netblock blocking (though only rudimentary until the final release).

If you want DirectAdmin to support it, you'll have to ask them. We won't ask them to until there's a final version and that probably won't be until the end of the month; we're still fine-turning our copy.

You don't need custombuild to convert to Dovecot; look here for instructions on coverting with customapache.
