After taking the evening and morning off I came back to way too much spam. We're talking thousands of messages, because of a need to monitor a catch-all account. I've been using a locally installed Outlook tool, but it doesn't give me much if I want to access mail through openwebmail or some other outside tool. So...
What are you using to manage spam? I've seen that there are a variety of companies out there offering solutions, but deciding which solution seems more difficult then dealing with the spam. Add to that that I am running a Raq 4 with the 550 OS, and I wonder, which solution do I buy - the one for the 550?
Any help would be appreciated ---
BTW: I've been thinking about the solution below as it seems like a good balance.
I guess my problem with that is the same as many others in my position. I don't want to miss mail and I want to be able to manage the mail that I am getting in an effective way. The reason that I have been looking at SpamAssassin is that it apparently has an option to simply flag, by changing the subject, mail that is potentially spam.
Yes, that is a good alternative. You will use more of the CPU on your machine if you're doing spam processing as well as other services, so take that into consideration, especially as you're on a RaQ 4 CPU. It should work fine, but you might need to watch out for dynamic web stuff, large logrotation jobs, etc. that might cause low memory/high CPU usage errors from Active Monitor. Sporadic reports I wouldn't worry about; if you're getting them all the time, you've got too much going on at once for the hardware to handle.
By selecting reputable DNSBLs false rejections are kept to a minimum. Also don't forget you can customize the bounce message each DNSBL "hit" returns to the sender, providing a URL to a page explaining your spam policy and providing an alternate contact method (form to mail, Gmail account, etc). Legit senders will see the bounce message and be able to follow up.
I should have asked this the first time - what's a RNSBL?
My fear in the methodology that you're referring to is that it sounds really complex, and I am not a complex person. I like things simple. I can simply pay someone for an installed PKG and then I don't have to learn Linux.
I guess the other side of this that's somewhat unique. I am currently hosting only personal sites on the RAQ and don't intend, at any time, to have customers hosting on the RAQ. The good news is that all my high CPU sites are on Wintel boxes, because that's my main knowledgebase and I don't worry too much about losing a little CPU or memory here or there. If it gets to be too much I'll move it to another box. As it is now I have a few of these installed and powered on, even though they're not connected to the net, because I like how they look in my rack.
It's not too complex. See my HOWTO at http://www.cobaltfaqs.com/index.php?...spam_blocking, and decide if you want to try it or not. The process has you back up your original config file, so if it doesn't work properly, you can easily restore it back to a known good setup.
You can setup Symantec's SMTP gateway on a small box to filter your e-mail before forwarding it to your main mail server. You can set this software up to scan/filter for viruses, SPAM, etc. It will also queue e-mail for you if your main server is down and forward it when it's back up. Maybe a solution for you or maybe not. Hope this helps.
After much debate, mostly because I'm cheap, I decided on SpamAssassin as a standalone product to try and battle the issues that I was having with Spam. I did some research and settled on buying from Brian at Nuonce.net who had a SpamAssassin RAQ550 .pkg with built in interface. The results have proven to be awesome and I am now getting less than 25 spam a day whereas I used to get 1000s. This is a product that I would highly recommend for anyone looking for a good, inexpensive solution to fight Spam at a global and user level.
