I’m looking for some software that hopefully integrates into Notes/Domino that puts all e-mail into a holding area until the user who it is addressed to decides that they want to accept messages from that address/domain.
As everyone else does, we have a horrible spam problem, and I see this as the only 100% solution. It will be a pain for the first month or so until the majority of addresses are allowed, but after that should be clear sailing. Of course all messages from our server will be allowed thru without being quarantined.
Not sure of a solution exactly like that, however, I would suggest you look at either Chris Linfoot’s blog @ http://chris-linfoot.net/ to get tips on implementing an anti-spam solution directly in domino, or look into a device such as a WatchGuard Firebox (www.watchguard.com) with Ultimate Threat Management or at least the spamBlocker subscription. I really believe the “proper place” to reduce spam is at the firewall, and keep the load off the domino server. We use the Watchguard x550e with the UTM, and have found it to be excellent at reducing about 98% of our spam traffic (with no interruption to the users). It has the capability to block, quarantine, or pass on the the spam at three levels (confirmed spam, suspected spam, and bulk email) as well as giving the user a way to retreive messages quarantined. Its very well priced (the x550e was approx $1500 for the UTM package, and renewal is somewhere around $600 a year) … which I beleive is worth every dime, especially if you are looking to make each user decide who they can receive email from…
Jeremy has some good answers. I can only add that you may want to look at Postini, depending on the size of your organization. It is very competitively priced, you get the quarantine, it has excellent tech support, and the users are responsible for their own quarantine (which makes your job as an admin, easier).
There are other solutions as well, but you have to decide if you want to manage them or have someone else do it.
Thank you for the info. We use a Microsoft ISA server as our firewall. That does the E-Mail address validation to keep the messages that have our domain but not a valid user address in them from the server. We also run Computer Associate’s Secure Content Manager which flags about 80% of the spam e-mails, but we still get a lot of junk.
I think we’re too small for Positini with only about 250 users, but I will be looking into their services too.
