For months ive been battling spam and other crappy stuff so i made a jump for a IronPort C10 (yea yea its the bottom of the barrel) but this thing works great for my needs and my users (family and friends).
My old load on my mail server was .8 all the time or higher now shes around .2
What are the best ways to block outgoing spam? Installing APF would help ful?
Any other idea for outgoing spam?
I have a client who is not happy with their current hosting provider. They get a significant amount of spam to their email addresses. Are there any providers you can recommend that offer good spam protection?

We have 3-4 business websites and spam, especially within the last 6 months, has become a tremendous problem. At least 100 spam emails a day are being delivered.
Spam filters do not solve the problem - they simply put some percentage of spam in a folder, often genuine emails, and we still have to go through it manually.
Do not mind paying a premium for the hosting. Any hosts that offer HEAVY DUTY spam protection?
I have 5 Linux Plesk 12 servers, and I use Spamassassin, usually at a sensitivity of 2 or 3, I also use the following DNS
Blackhole lists: zen. spamhaus. org;b. barracudacentral.org;abuse.rfc-ignorant.org;cbl.abuseat.org;bl.spamcop.net;nomail.rhsbl.sorbs.net
But all of this seems to have minimal effect. I examine spam that comes through which looks very obviously like spam, but Spamassassin gives it a very low score, usually in the negative numbers.
Is SA just not as effective as I thought? Seems like if Gmail, etc can filter spam so effectively, then why can't SA? If there's something I'm not doing right, or what you all do to combat spam with Plesk 12.
I have some error when the new outgoing spam protection (limitation for outgoing mail) is enabled. Mail clients are unable to use SMTP for sending mails. "My mail client says: The message could not be sent. You are not allowed to use sendmail utility."
I don't undestand the blocking behaviour since the checkbox "Allow scripts and users to use Sendmail" is checked and no limit is exeeded.This is the relevant log part of maillog:

View 1 Replies View RelatedI am interested to setup two Ironport appliances in my company network. As the current company is about 120 users, and each user send and receive an average of 100 email per day (including newsletter, signup, etc) it’s about 12000 email a day.
I am interested in :
For the mail side of the company, I am thinking about an Ironport C150 and for web filtering, I am thinking about S350. The current company outgoing banwidth is 60 Mbit/s at peaks, but I want to be able to be able to continue to use it with traffic up to 200 Mbit/s, as we will maybe take some server in the company network in a few months.
Some questions :
- Is it really « setup and forget » appliances (except monitoring them)?
- Are they hard to setup and configure?
- Do they support many email languages?
- What is the price for both appliance, like around 5k each, 10k each?
I am looking for some good ddos protection providers, via protected dns. I've searched on internet, but most of them are really expensive.

I see in the plesk documentation that the screen to enable SPAM filtering for an individual there is an option to "Move spam to the Spam folder". I don't see that option so I am wondering if it is only available on some versions of Plesk, or in combination with certain mail servers. How to make that option available?
Hey guys If there was a way to have the ips of the dedi change constantly would this help prevent ddos attacks or would there be no difference if the domain was being attacked.

Do you guys have any recommendations for any DDoS protected hosting? He doesn't really want to pay more, if he doesn't have to.

View 11 Replies View RelatedAs we prepare to ramp up new networks, we are looking at different network attack protection devices such as Intruguard.
I am interested in input on other devices out there, or ideas using devices to protect against flood attacks and DDOS on a network that is under a gig in speed (100-200 Mbps).
Is bound to happen to my server one day or another (get attacked). So I need help deciding whether to get a DDoS protection server now or later. Or pay as I go (I'll explain this in a bit).
First of all I am considering getting this because I want to use this server to hide the real source where people are downloading from. People connect only through FTP server and download. Of course if I give the real IP away I am subject to attack at anytime from anyone.
I think if I buy a server somewhere else and have people connect to there then that server will connect to the real server if I was to get attacked the server I bought "somewhere" else would only get attacked which would or would not be protected by a that special company who protects for these kind of things.
Only downside so far is I have been able to have the method above done. A person connects from one server which connects to the real server they will be downloading from BUT I use up to 2x bandwidth. Because when someone requests a file from server A...server B sends to server A then sends back to the user requesting it. A process that well works but anyone know if instead of sending back to Server A it will go directly to the user without exposing any info on the real server?
When I meant "pay as you go" I mean have a server with a DDoS protection company but don't get any protection until it happens rather than waiting on the last minute before switching to them (like adding new users now but those users knowing the real source).
These "users" downloading do about 106GB average. So you can see how big a downside is having to use 2x of bandwidth from the method I know above. The companies I am on do not have DDoS protection that I know of so I am forced to look for external companies to use to connect to the real source.
-So far everyone knows the real source IP but that is because I trust them. Anyone else is waiting to get on it and me looking for ways to put them on.
//hopefully you enjoyed my big paragraphs.
-And what kind of "protection" would I need if only FTP is being used since there is "specialized" kind of filtering on attacks.
I was located in modvps.com, but I was asked to find another hosting because of DDoS attacks on my VPS.

Is there a way to enable hotlink protection so that when I edit a page from my computer the pictures from the server display from my server but my site is still protected from other hotlinking. My intent is to make it easier for someone to edit there page.(i know I could just reupload image files but I was trying to think of a way to make it easier for someone else) I thought adding my ip address to the cpanel hotlink protection enabler would do the trick but it hasn't.
View 4 Replies View Relatedwanting to password protect a directory and all FILES and DIRECTORIES under it as well.
I have tried the password protection system in plesk, simply put it doesnt work, sometimes it just doesnt restrict any access and the files can still be downloaded / accessed, and sometimes it asks for a password but even if typing the correct info it sais its a wrong password.
each time i setup the p/w i do it the exact same way, but its random about when it works and when it doesnt.
So, i tried the simple .htaccess way, and i still get the same problem. Can someone reccomend something to me? maybe a free php script that can do this? i need something fairly secure, doesnt need to be some super duper crazy script but at least so people cant just download the file containing the passwords and then they have access.
I have a plesk panel and i had a look for hotlink protection but unfortunately couldn`t find the proper option.
I guess there is a hotlink protection at windows version of plesk but not at linux one. I have a linux server.
Also i have a question about hotlinks also, one of my customer has a site that it uses too much bandwith like 600 gb at a month. It is an education related site and site is html.
And i am having some high load issues. When i check apache-status it shows %90 of the connections for that site. But i cant be sure that if it site really makes high load on server because like i told site is html. Also would like to know if server get s load for example if visitor wants to download something from site.
Because visitors are usually downloading zip, mp3 and those kind of files and i dont know if that many download cause the high load.
Also will it reduce the load of the server if i put hotlink protection to that site because of chance for other sites to leech files from this site?
Edit : If there isn`t any option for hotlink protection at Plesk panel how can i enable hotlink protection. Maybe using htaccess, but i would be glad if you can provide hotlink protection code also
Anybody have good experiences with some software based Apache 2.2 ddos protection. Im trying to find something similar then mod_evasive.
It's just that evasive won't work with Apache 2.2. It actually works, but it does not do what it is supposed to do.
Have tryed many different configuration, but it just won't do it.
After Googling i found out that many have suffered same kind of experiences with mod_Evasive and Apache2.2
I guess it is not working cos we got Peruser there. http://www.telana.com/peruser.php
Means that there is many differend child processes and evasive don't share data between childs.
So suggest me something. This is coming on prodution server with hundreds of domains so it has to be stable, fast and rock solid.
I have a budget of $20 monthly. I want to get a VPS, 500+ram, 15+gb, DDOS protection, managed, cpanel preferred. Which BIG webhost do you guys recommend? The webhost need to be big.

I was looking for a basic DoS protection against scriptkiddys.
I heard nginx is better as apache against DoS attacks.
if your web host has some hardware ddos protection and i'm assuming it blocks the ip address/addresses of a DDOS attack, will it Unblock that ip address/addresses after a certain amount of time?
Because a person's computer may unknowingly be part of a botnet that does a ddos attack, and that innocent person won't be able to access the server if their ip address is not unblocked by the ddos hardware right?
