But i was wondering, is there a good opensource based tool for this?
for a server-wide anti-spam solution I can implement on a Linux server. The mail queues are constantly getting backlogged with thousands of messages which bring the servers to a crawl. There are really two issues the solution needs to address.
1) Spam
2) Spam sent to other people that have the from address forged with our clients' email addresses.
We have spam assassin installed for individuals to use, but there's got to be some sort of solution that can clear out the vast majority of the junk before it even gets to the queue.
It probably goes without saying, but the solution needs to be open-source or have a very inexpensive license.
I just found out all my mails sent to Gmail are marked as spam. However, if I check my IP address in independant grass-root spam databases, my IP address isn't blacklisted. I checked 7 of them. Do you know how to solve this problem
View 6 Replies View RelatedI am running Win2003 server with Plesk 8.3. Antivirus running is F-Prot. Me and my clients have been getting a lot of spam emails and I am looking for suggestions on how to stop them. Plesk seems to provide some options for checking blacklisted spam servers but I was not too satisfied with the result. Maybe I was not looking up the right urls?
So, any suggestions on blocking the spam would be welcome. I am ready to pay for it too...but I am on a very tight budget. A free solution would be the best for me at the moment.
I also used SpamAssasin for a time being but it did not work out to any of my client's satisfaction even after a month's "training" of SpamAssasin.
I am interested in ASSP as a anti-spam tool and have heard good things, but I have 1 question I can't seem to find an answer too.
With ASSP is there a way to screen image spam like you can with FuzzyOCR? With ASSP do you even need to scan images at all? Because it waits for the sending server to respond for authentication?
I was running MailScanner / SpamAssasin / FuzzyOCR combo with a couple of chron jobs (to sweep fake bounce email out of the mail que for example) with very effective results, but it took forever to tweak all three to reduce server load. MailScanner was breaking webmail randomly so I have it disabled currently so I get a lot more spam.
where i can buy some cheap spam protection appliance. Right now, we are buying from mailfoundry, but it is a little bit expensive. I send an email to can spam, but i was quoted 18 K anually, to protect 25K emails. Anyone, have a way to buy some cheap anti-spam appliances.

You will find many Anti spam blocker tools available in market. I recently come to know about[url]
. It’s an excellent tool to encrypt your email account if you use to display it on your website.
Generally, spammers uses robots (some kind of crawler) to get email accounts from websites. Once they get it they start selling it to other spammers and will start sending spoofing emails.
This tool will help you to encrypt your email address and stop spam coming from your website
i have a ironport and its coming close to my renew, frankly for my 50 and less users its expensive and i end up with a so so of a server.
my goal would be to use a vm based one for power "green" and backups/migration needs.
im runing scalix with clamav/spamass
Does anyone have any experience to share concerning these devices?
I'm having some serious spam issues and would like to look into a better approach to preventing this than the typical SpamAssasin solution bundled with cPanel, Plesk and so on. SA seems rather inefficient, needs a lot of training, can get a lot of false positives, tends to break now and then, and so on.
Have any of you used either the Barracuda or the MailFoundry applicances, or even better - compared them first hand? Are there any similar solutions out there, perhaps cheaper/more cost effective in the long run?
$2000-3000+ for the hardware and around $500 a year for an anti-spam solution is a little steep in my opinion. Especially considering the old and cheap hardware for an example MailFoundry uses. How accurate they actually are in terms of false positives is also seemingly debated. MailFoundry promises a near 0 false positive rate, while some user-experiences suggest somewhere between 6-10% - which could represent an issue just as problematic as spam itself. Nobody wants to lose out on important email. To spend such an amount on a device and updates, it certainly needs to be worth it. Is it?
Are there any equally good or better software based solutions out there, that one could for an example use to set up a custom anti-spam server using existing hardware at the DC?
Does anybody know of any open source Anti Spam gateway for mail servers? I have used MailCleaner and know how it works. Is there any other available?
View 3 Replies View RelatedAs a web host or ISP what do you think is best to do? do spam/virus filtering, or don't touch mail and let the user do what they want with it? (no chance of false positives, or lost mail, this way)
I work for an ISP and we have a barracuda and we get tons of calls from customers regarding lost mail and such as when you're filtering such a large varitey of mail its very hard to have a "perfect" filter. Mail that a car dealership gets and what a hospital get is totally different, for example.
Also in terms of web hosting the filtering will put a reasonable load on the server during peak spamming hours.
So just curious, as a ISP/webhost customer do you think your host should do filter or do you rather manage that yourself?
We have identified that messages from your IP are being filtered based on the recommendations of the Symantec Brightmail filter as well as our internal Smart Screen Filters. The filter was initiated by Hotmail at (5/20/2009 12:00:00 AM) PST due to a large volume of emails that were sent prior to this time.
We will be happy to work directly with Symantec on your behalf to investigate and possibly resolve this problem. In order to move forward, we will need examples of the messages that were caught by the Brightmail filters.
I am running a small hosting operation and would like to know more about SPAM filtering and controlling. SpamAssasin is installed on my server but it does not do much. I was looking into different solution with a anti-spam device and would like to know which one is recommended the most: sonicwall, barracuda or symantec? (total email addresses is less than at thousand)
View 4 Replies View RelatedHow much CPU & RAM load does your spam filter put on your VPS? It seems logical that the more mailboxes hosted, the more VPS resources the spam filter will consume - especially if any of the email addresses are targeted by spammers (or the user is careless and gives out their email address everywhere - as many do).
It's become so much with some of our subscribers that we have had to offer a hardware spam filter, to keep the load off the VPS. It's been great in that the VPS's protected by it have seen a dramatic performance increase....but are these subscribers unique in some way?
And so here is my question...how much CPU is everyone's spam assassin/spam filter using and how many mailboxes do you host on your VPS? very curious...
Anyone else have problems with Yahoo Spam filters being overzealous? I recently setup a new domain and a few email accounts. After sending a few test messages to my Yahoo email, each one of them was flagged as spam. I changed the text to a more regular email, with no controversial words and still the same result. I notice that Yahoo regularly traps some newsletters I subscribe to in my spam filter, but rarely, if ever legitimate emails. I checked with my web host who informed me they are not on any spam blacklists and that I would have to contact Yahoo. Yahoo's help is quite a maze (designed to make you lose interest and move on), so before I continue hunting for how to contact Y!, I thought I would come here to see if this is a common problem (with a common fix).
View 1 Replies View RelatedI'm wondering if theres anything I can install on the server that will either filter or track outgoing spam. I don't want to limit the number of emails sent per hour or anything, I just want to be able to maybe search through some flagged emails or something. Or if they send the exact same email more than x times it can disable their account... I'm not sure
View 1 Replies View RelatedA few months before I updated to Plesk 12 I noticed a huge jump in uncaught spam - I hoped the update to Plesk 12 might solve this but no luck.
I have now changed the spam sensitivity on my account 1, the idea being I would then whitelist the domains I want to get through but literally nothing is getting marked as spam. Users on other domains on the same server are reporting the same.
I'm using the following blacklist database lists:
zen.spamhaus.org;dnsbl.dronebl.org;bl.spameatingmonkey.net;psbl.surriel.com;b.barracudacentral.org
I have Plesk SpamAssassin 3.3.2 installed and set as the Spam handler.
My server is Win2003 Standard with IIS 6. I'm using IIS6 to host websites but i have a need to run subversion which require Apache. I'm wondering would it cause any problem with my current operation. Apache will run on different port than the standard 80.

View 2 Replies View RelatedI am happily running Plesk 11.5; with just one small but annoying persistent problem:
I have Clients with large mailinglistes
- SpamAssassin
- Server-wide greylisting
- DNSBL
is running.
But apparently many of the lists mail addresses have been harvested over the years. And as there is no easy way to use SA in mailman, I am down to greylisting only for list addresses.
This results in insanely large amounts of SPAM (-> moderation requests) on the client's lists. Is this behavior improved in Plesk 12?
Or can probably SIEVE filters work here - are those available to mailman? (probably not as they work in Dovecot?)
Almost all mail adresses on my server is getting a spam mail from same mail marketing company everyday and i want to block them... Normally i just add the mail address to blacklist from "Spam Filter Settings" but this company is opening new addresses everyday and it is impossible to add all of them to blacklist so i need adding it as a regex to the blacklist...
The company i am talking about is opening mail addresses every day like below...
nrt150401@hotmail.com
nrt150402@gmail.com
nrt150403@yandex.com
nrt150404@mynet.com
As you can see all mail addresses begin with "nrt"+"6 digits of day"+"free mail provider", so right now i am using the regex below and it is already added to the blacklist but they are still able to send me... What can i do now?
I can only add 100 addresses to the global address spam white list. I need to add more!

Seems like I'm having considerable problems with APF's antidos feature. I keep getting legit users banned from my site, and don't know how to stop it (other than disabling antidos altogether, but I guess there should be another way).
I've already set:
TRIG="100"
SF_TRIG="100"
...in the antidos configuration file but I'm still seeing more and more legit IPs getting added to ad.rules. I've read that raising or lowering LN="100" is the other tweak I should try, but there simply is no such value defined in my conf.antidos file.
Another thing I noticed that, although I only got two notification mails telling me about "attackers" blocked by antidos, there are roughly 40 entries in ad.rules. As a matter of fact, I don't understand what antidos is doing there in the first place. Seems like iptables doesn't log to var/log/messages anyway, at least not on my machine - so where is antidos getting those ips from?
