Exist any plug-in or way to configure the Exim to make it work as SpamArrest?

without the useless black lists... you know...

1-somebody sends an e-mail...
2-if the e-mail is on contactlist of the user... the mail is received...
3-if the mail is not... is send to a SPAM acount... and the "somebody" recibe an e-mail like this "you no autorize to write to somebody... do this or that to get autorized"

Blocklists may be useless for you; for me they block approximately 75-80% of the email coming into my server. With no more than two or three false positives per server per month.

And they notify every blocked sender without any activity on my part, so false blocks get fixed promptly.

There are both commercial and free solutions out there to do what you want on either your server or a separate server solution. They've been discussed previously on these forums; if you look, you'll find the discussions.

If you use any of them you'll become an instant spammer. I've discussed this before. The problem is that most spammers forge innocent parties email addresses as their senders. And that's where these programs send their notices.

Yes, you won't see the spam, but for almost every piece of spam received by your server, some innocent party is going to get spammed by your solution. You won't only look like a spammer, you'll be one.

Jeff.. tanks for you answer...
Here in Argentina the black lists block many good mails... because a lot of the ISP IP's are in those list...

I don't understand way i become a spammer...
if a spammer send a e-mail... the spammer (or the one hi put like sender) receives "you are not autorized to write to... etc.. etc.." anyone receives the spam as ben sended...

i can find the thread you mention... any idea what subject have?

Yes, that thread explains a lot. But there are actually a bunch of others.

The problem, Ramdileo, is as you write, the address he spammer used as the sender gets your email. Since the sender is almost never the spammer, but almost always a working address selected at random, for every 10,000 pieces of spam your system receives, you're going to send out 10,000 notices to people who never wrote you. That makes you a spammer who just sent out 10,000 pieces of spam.

systems like spamarrest has a list of recent senders... so, when a sender recibe the notification 2 o 3 times on a weak or month... the system don't send the notification anymore... (problem solved)

you say, the systems for DA, dont have this feature? thats the problem?

anyway i would be satisfied with a white list in the user panel... and exim sending the mails are not on that list to a [email protected]...
and the user can add addresses to that list sending a e-mail... like majordomo subscribe or some something like that...
without activate the spamassasing and their black lists...
 
The problem is not solved. I'm not going to add a SpamArrest-like feature to the exim.conf file because I believe the majority of the anti-spam community, and I agree with them. Of course you can add anything you like, or you can petition DirectAdmin's authors (there's even a sub forum for ithere) to add it themselves.

It appears now you're saying you'd like a whitelist in the user panel and that if the whitelist is used then for all email not on the whitelist, said mail be routed to a special spam address. Why @domino.com? it appears to be an inactive domain, and for sale. Is it your domain? If not, why would you send the email there?

I suppose this could be done on a domain-level basis. On a user-level it would be much more complex.

I don't see any reason for it to be included in DirectAdmin, though, unless a lot of people request it, and mis-setting it could result in all email being routed to a spam address.

Maybe I am not thinking right about this... this system "boxtrapper" or "challenge" or whatever, seems a little strange to me. If you want to put it after all your regular filters, you can still get good mail lost. If you use it instead of all the regular filters, yea, I agree you would be a spammer. Seems to me the best plan is to just find and use the best filters possible, and delete the few emails that come in. I am using spamblocker 3.0 (thanks Jeff!) and also SpamAssassin, and 99.5% of all spam is caught and removed. Is the "boxtrapper" supposed to do better? Is the purpose to remove that last .5% of spam, or to use instead of regular filters to reduce the about of missed good mail? What if good mail is in the form of a form-mail (unchecked by anybody)? Often times, UCSD and I am sure other universities send out important student correspondence in the form or form-letters. Does this mean these mails would be lost with a "box-trapper"?

I am just seeking understanding, if you don't have time, don't bother answering this, I have happy with my 99.5%, I just like to know all I can.
