I am looking into implementing an antivirus/spam relay server using Postfix + MailScanner + SpamAssassin. Does anyone here have experience with this kind of solution?
What kind of rough performance in messages/hour or messages/day could I expect from a server like this:
PowerEdge 2950
2x QuadCore Xeon E5320 (1.8GHz)
8GB RAM
4x 146GB 15,000rpm SAS in RAID 10
I installed ClamAv from WHM, but i can see some process name "Mail Scanner" in top command on my CentOs server ....

is there any mailscanner control panel available for cpanel? we have install mailscanner but cpanel user can play with whitelist, or disable and enable it
View 1 Replies View RelatedIs there any way to define black lists for a specific domain?
Like, a file for each user: user1.cf, user2.cf.
And when that user receives email, Mailscanner will check server-wide filter AND domain specific filter.
Any advanced MS/SA users?
I've downloaded and installed MailScanner using:
[url]
Now.. can anyone tell me a good "how to" to configure MailScanner to avoid a resource hog and to ensure email can work ok and stop incoming spam as well?
which one of these three spam scanners is the best one Spamassassin, dspam or mailscanner?
Currently i ahve spamassassin installed and it doesnt perform so well,i get 10+ mspam messages per each normal message.
Recently installed MailScanner using chirpy's script. Everything is fine.. but the big problem is that the load average is very high after installed this software.
Server is RedHat ES 4 + cPanel - Dual Xeon CPU 3.20GHz x 4 procs. 2 GB RAM with high e-mail traffic.
Can anyone give me some tips to configure MailScanner to stop spam and avoid a high load average?
Maybe you can tell me what variables are u using in the config file..
My sever is running mailscanner-4.56.8-1. Of late many of our customers complain that mails send To and From our server take hours to be delievered.
I tested this myself by sending test emails to and from my hotmail account which took long time to be received and delivered.
Also, in /var/log/maillog i see entries such as the one below;
"Jan 4 20:39:36 www MailScanner[8461]: New Batch: Found 17678 messages waiting "
So i understand there is about 18 thousand emails in MailScanner /var/spool/mqueue.in folder.
To test i stopped MailScanner and started Sendmail, i send an email to my hotmail id and it got delievered immediately, but when i restart MailScanner and resend the same message it took 20mins to get delievered.
- how do i improve MailScanner processing so that messages are delivered faster?
- Do i need to change the "Max Children = 5" variable in /etc/MailScanner/MailScanner.conf?
- how do i force delivery of the 18thousand emails in mqueue.in folder?
I am using dreamhost host 3 of my web sites and 1 blog. Dreamhost is great, offers alot space and bandwidth.
but I think they are oversellling their space, sometimes it gets really slow. (overselling ? ok, I dont really know, but sometimes its really slow, and most my asian readers said need to refresh to load the page. I am wondering if theres a way to check if they are overselling or not.)
I am thinking about buying vps, even tho, I still got 5 month left with dreamhost.
I found 2 vps companies are highly recommanded on this forum, JaguarPC and LiquidWeb.
theres already a post compared both companies in terms of price and service. I say I will pick JagarPc, cuz, its basic plan just 20 USD, and htey got promotion now, its even cheaper. and basic Liquidweb vps plan is 60 bucks.
I am wondering why Jagarpc is so cheap , are they overselling? how can we check if they are overselling.
I found a few posts saying how good jaguarPc is. and they are not overselling, but those members just signed up this month, and only have 1-3 posts. I cannot really trust those new members.
Can someone share their experience with JaguarPC? compare JaguarPc performance and liquidweb performance. antoher question is switch from dreamhost to JaguarPC basic vPS plan, will performance gets better?
last question: VPS account allows 3 IP, 3ip = 3 domains? if not, how many domains can I have?
My main goal was stopping incomingo spam.. and MailScanner is doing a great work on that.. but, it is taking too much time extracting and scanning attachments... does anyone know how to disable scanning the attachments ?
This is my top output from MailScanner running:
Code:

I was trying to install mailscanner on a cpanel box using chirpy's script [url], followed every step, until this:
Code:
[root@server.yourbox.com:~]perl mscpanel.pl -i
Unable to open spam.scanning.rules for reading: file or directory doesnt exist at mscpanel.pl line 115.
On the 115 line i found this:
Code:
open (IN, "</usr/mailscanner/etc/rules/spam.scanning.rules") or die "Unable to open spam.scanning.rules for reading: $!";
The file /usr/mailscanner/etc/rules/spam.scanning.rules just doesnt exists... maybe chirpy's script is not working well installing everything its needed..
ClamAV or AVG ?
which one is better ?
ClamAV or AVG
and how should i scan my folder with ClamAV ?
My hosting provider (which will go unnamed because I doubt they would appreciate me broadcasting the fact that their server-based antivirus software isn't working properly) is experiencing almost daily email delivery failures on multiple shared servers because ClamAV stops working. They say they are running the latest stable versions of exim and ClamAV, but that "there is no guarantee...that the clamav error will not happen again". Right around the time this started happening, there was an article on the ComputerWorld web site (http://www.computerworld.com/action/...icleId=9077638) about a ClamAV patch being released to fix a security vulnerability. I'm wondering whether that patch was buggy, and whether other hosting providers are having problems with ClamAV. (It would probably be a good idea not to mention any providers by name because of the security implications.)

View 3 Replies View RelatedI would like to ask whether should we use/enable the clamAV service on our VPS? I have read from several article, it said that ClamAV is pretty hungry on CPU/Memory resources.
I would like to know, do you use/enable the clamAV on your VPS? Or even don't have it installed on your VPS?
How can I disable clamav on cpanel server and make sure that it's not running
because when clamav is running the outlook is not working so I have to restart clamav every time.
I have it installed on server, but sometimes it's dead, but no warning from system. It will prevent emails working then. So I wonder if there is any way to check clamav? when it's not working, system will release an email to the admin?

A few weeks ago I installed clamav using the cPanel "Manage Plug-Ins". It all seemed fine but my server load kept going ridiculously high. I couldn't work out what was wrong until I managed to get a ps aux when it was very high and found that clamd was using ridiculous amounts of memory/cpu. It's not such a big deal having it on my server, so I decide to uninstall it. After uninstalling it, MySQL started to randomly turn off regularly (around every 30 minutes). I tried forcing a cPanel update, updating the MySQL files, reinstalling MySQL, etc. but nothing has seemed to fix it. So as a last resort, I've reinstalled Clamav and now my MySQL is fine but my server load keeps going ridiculously high again; causing problems still.
Has anyone/cPanel ever experienced this problem? I need to find a solution as almost every account on my server uses MySQL as a basis for their website, so I can't have it going down even for less than a minute.
I've got ClamAV installed on my cPanel (Dedicated) server with a single site and would am having trouble setting up ClamAV to scan emails.
I installed it via WHM and have set it up in WHM to scan all items.
Ie: WHM -> Plugins -> Configure ClamAV Scanner -> Scan ALL items
After doing a few manual scans however (using 'clamscan -ri') I'm finding infections in the account mail folder.
1. Is there a good guide to setting up ClamAV on a cPanel serve do do automatic mail scanning? I was under the impression that ClamAV scans emails also however after doing some reading people seem to recommend MailScanner.
2. My logwatch is giving me the following error.
The ClamAV update process (freshclam daemon) was not running! If you no longer wish to run freshclam, deleting the freshclam.log file will suppress this error message.
The freshclam daemon wasn't running so I've started it (freshclam --daemon). I've also checked the freshclam.conf file and the logrile is set as follows:
UpdateLogFile /var/log/freshclam.log
I installed clamavconnector from Plugins sections at WHM, but after installing, i dont see any option about Clamd or Clamav in WHM, where should I go to use this tool?
Im running latest release version + RHE 4
Ok so clamavconnector has been running for like 3hrs and this is a brand new server i just got yesterday so theres hardly any files but clamavconnector is using 99% of 1 of my CPUs which i think is a bit mad. You think its frozen or somthing and should i kill it or keep it running?
View 6 Replies View RelatedI am recently trying to install the ClamAV program onto my servers. Everything goes well and it is able to get installed but I am encountering some problems.
1) The program keeps recurring the scanning process on my /home directory and will not stop looping.... I waited for around 12 hours but it still keeps looping....
2) I have started the clamd and tested it out by loading a virus onto my server... Nothing happens... the file still is able to be uploaded and excuted....
Is there anyway for ClamAV to auto scan everything that gets uploaded or transmitted into the server? And also mail me its daily scan logs that is issue to be stored in a specific directory.
I tried to install clamav, but i'm out of luck. It won't install at all. it gives the folloing error:
