Under the messaging configuration on the “SMTP Inbound Controls” tab there is the field “Deny messages from the following internet addresses/domains”. I have been usin this field along with the blacklist to effectively eliminate spam, but I can’t seem to block domains using wildcards. For instance I wanted to block messages from anything that was “.ro” like “mail.ro” or “spam.ro”. But adding “*.ro” to the field has not accomplished this. Any Ideas?
Also, Is there an effective method to block spam from users of hotmail, msn, yahoo, ect…?
Thanks!

Jason,
The standard rules can’t block based on the type of client which sent the spam… no.Spam.domino can do this and therefore allows you to block/filter the most used spam sending mailers as well as creating rules using wildcards and pattern matching filters… check it out at:

If you want a way to get rid of rules completely check out SpamSentinel. It has worked really well for me!

I’ve put in a formal complaint to the company. Doubt it will do much good, but still…

I’ve had success at using the tools you mention (inbound restrictions & blacklists) in conjunction with Server Rules. In R5, all we really had was inbound restrictions so those restricted domains are still in my config doc and are still being honored. However, turning on the blacklist feature really started blocking a lot of SPAM, and then when I created/refined some Server Rules (moving SPAM into a quarantine database), I’ve greatly reduced the number of junk messages that get to users. So I’d recommend defining and implementing some Server Rules that look for typical SPAM in the subject and/or body of messages and I’ll think you’ll have good results.

Can you give me an example of some of your server rules?
Thanks!
Subject: RE: SMTP Inbound - Blocking Domains - SPAM
Here are my server rules, gleaned from watching several users’ mailboxes who got the most SPAM. Also, in one of the LSphere sessions, they recommended keeping all of your logical operators (“AND” & “OR”) together. While my rules all use OR, I went ahead and split them up by what I’m looking at (sender, body or subject) so it’s easier for me to look at. Also, you can reorder them in the Rules view because they’re evaluated in the order shown, so you want to put the rule(s) that you think will trap the most SPAM at the top of the list so that it doesn’t have to waste time trolling through rules before it finds one that’s a hit.

To block all mail from a particular geographic TLD, try http://blackholes.us. There are lists there that can be used with the DNSRBL functionality of ND6 and can reject whole countries.
DNSRBL works on IP, not domain, which is a more reliable way to block generally as domains are easily changed.
Blocking at the client isn’t blocking at all - you have already accepted the message. If you make a server rule to send an NDR after the spam has arraived, the NDR will most probably never be delivered, or will be delivered to the wrong place. The spammer is not interested in your bounces.
