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?
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..
I installed ClamAv from WHM, but i can see some process name "Mail Scanner" in top command on my CentOs server ....
View 6 Replies View Relatedis 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 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
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.
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?
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:
12:10 3 MailScanner: extracting attachments
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..
I'm running low on space ever since switching to incremental backup. I don't want to switch back to the full backups because the gzip was killing the server for an hour every night...
I have the following setting turned on:
Backup SQL Databases : "Per Account and Entire MySQL Directory"
Will I get a full backup if I just do "Per Account" or am I missing something if I set it that way?
I have some extra space on The Planet's NAS backup at /mnt/backup but not enough for the full backup. If I could split the backup in two that could work as well.
I have some question regards configuring a cPanel DNSonly
server. What I have done so far is that I have a VPS in an other DC, in an other country then were my servers are. cPanel DNSonly is installed and right now I am wondering have I done it all in a proper/correct way and how can I test it to see if it will work without bringing server down of course :-)
I made all servers in the cluster on the DNSonly server the DNS role to Standalone, is that ok, and if not why???
Will the DNSonly server then operate as the backup? On the dedicated server side I added it in the cluster and told it to synchronise changes. So I assume the dedicated server will send changes to the DNSonly server, is that correct?
If I make all servers on the DNSonly (VPS) instead of Standalone to status: Synchronize changes, will all servers get from each other as will in that cluster all the zonefiles?
Sorry, I am a bit in the dark with this :-)
Can I change the second name server on each dedicated server to point to the main IP of the DNSonly server? the VPS main IP.
What can I do to test it for correct working?
Is it a good thing to have a second VPs geographic other side of world to do the same with, will that help in more reliable dns and even faster to find websites for my customers?
The latest cPanel DNSonly version doesn't allow me to view the CSF firewall to display, It is working, but nothing to configure from the WHM, I can of course set the firewall specific rules, but one of the VPS hosters recommend to run without firewall as he said nothing to be worried about? Any advice in this? is that true?
is cPanel DNSonly a good solution for a redundant DNS? Are there any other easier options for a cPanel/WHM based config?
Any live expirience for good values of this courier settings for cPanel server:
Maximum Imap Connections (Total)
Maximum Imap Connections Per Ip
Maximum TLS/SSL Imap Connections Per Ip
Maximum Pop3 Connections (Total)
Maximum Pop3 Connections Per Ip
Maximum TLS/SSL Pop3 Connections Per Ip
Number of Authentication Daemons
?
The current values are the original ones which cPanel set:
Maximum Imap Connections (Total) 50
Maximum Imap Connections Per Ip 30
Maximum TLS/SSL Imap Connections Per Ip 30
Maximum Pop3 Connections (Total) 50
Maximum Pop3 Connections Per Ip 4
Maximum TLS/SSL Pop3 Connections Per Ip 30
Number of Authentication Daemons 5
Thanks,
Is it possible to change all the addon domains in a cPanel account from :fail: to :blackhole: without having to change each domain manually?
If your wondering why they need to be changed to blackhole, lets say that somebody has a lot of inbound spam which is filling up the mail queue.
