MailScanner- Thousands Of Mails In Mqueue.in
Jan 4, 2007
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?

Currently i'm migrating all my domains from ensim to Plesk.
I use for this the Plesk migration tool.
From the moment I change the nameservers, some mail will still be delivered (for a while) to the old ensim server and not the new plesk server.
How can I move or migrated mail from mqueue to the correspondening account under Qmail?
Because the ensim server is configured to be the final destination for mail . I cannot add extra MX records with a lower destination.
Or can i change easly the ensim server to be not the final destination)?

Currently, we use powerdns with mysql replication on multiple servers. This solution is kindda okay for now but I'd like to know if there is any other better solutions than powerdns.

For the last 6 months our site has been under severe brute force, syn flood attack. They keep bombarding a single URL of the server and it is xml file. They are not attacking any other URL.
We have removed the xml page from our site but still they keep on sending requests, this is for the last 6 months non stop.
The IP has been changed just to see and they are sending several thousand requests per second. The requests come from different IPS and different ranges, so you can not even block the IP’s. They seem to be coming from a legitimate IP’s.
Due to this I have had to pay for an extremely expensive server which holds 8 GB of RAM and quad core processor etc, however, even with this the server server still reaches critical level, just because these requests are eating up my resources.
Our technical team has been working on all aspects of apache server security, external modules, firewall, hardware firewall from beginning but still we are not able to stop them.
We have installed following modules.
4) mod_security
5) mod_evasive
6) Firewall
7) SYS_Cookies enabled
We have worked with the hosting company and their technical team leader, he installed the best CISCO hardware firewall and tried to stop them, but in vain.
We have checked our server to see if anything from our site is causing the request, no extra file uploaded on to the server. For example if some file has been upload or some text has been added to the file (checked if we’ve been hacked). Even though we checked for any hacks, I am still wondering if there is something we do not know about. Can a hack lead to huge amounts of traffic?
We need some help to stop these attacks. We have searched a lot and have found that sites that get attacked like this have only one option is to shut down till it stops. I really hope that will not be the case for us. Please let us know if any one has any ideas to deal with this.
Also could it be our own part of php code which can do this? We are ready to check every php file to make sure it does not have any line of code which can be dangerous?
We worked with hardware firewall company to drop a request on the spot coming for the single URL but it is getting setup.
We have antivirus running on server however if any specific antivirus or antimalware is needed, we can try that.
Following are the details I have got from my linux admin. This will help you to trace the issue in better way.

I have a file that will probably be a few megabytes in size that will be downloaded 100's of thousands if not millions of times.
Where would be a good place to store this file?
Are there any big file hosting companies out there you've used or can at least recommend for this sort of thing?

I am running a very successful wiki based website that has outgrown our current web host. The site runs very slow because our host says we are hitting the memory limit on the server (currently under a shard hosting plan).
Thousands of visitors per day
Ten thousand page views per day (all PHP)
20GB bandwidth per month

OS: CentOS 5.1 32 bit fully updated.
I'm trying to tar a folder that has 100's of thousands of files and I ensured that no files are being added or modified in that folder while the below command is being executed:
nice --adjustment=20 tar -cf users_from.tar users_from
I've tried it multiple times and it always stops before it finishes and ends up with a corrupted .tar file which gives errors when extracted and is obviously missing a lot of files. Sometimes it creates 200+ MB, sometimes 50 MB before it stops.
I also have enough RAM + swap for the operation so that can't be the cause.
So is it just impossible to tar a directory with so many files and is it even possible to get a list of the files in that directory?

Is 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

For the last 5 days, exim has been retrying to resend email to a recipent every
1 millisecond.
As result, logs are huge, and load is being affected.
So I'd like to know how can I set/configure exim to ingore sending to any
email I'd tell it.
I mean is there any config file I can look into, to set a ignore list, or even
how to have it so that it retries sending every 1 hour, instead of every 1 millisecond.

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 am having problem with a server. On all sites on the server start appearing core.xxxx files that in result fill server. Quotas were disabled because some people had issues logging in on because of error.
Quote:
Sorry for the inconvenience!
The filesystem mounted at /home/*** on this server is running out of disk space. cPanel operations have been temporarily suspended to prevent something bad from happening.
Please ask your system admin to remove any files not in use on that partition.
how to remove all of them so they dont appear again, on some sites there are thousands of core.xxxx files and weigh over 60GB.

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..

We're absolutely unable to track or find out who is sending it or how to stop this.
So I'm wondering if it is possible to prevent sendmail from sending to:
lsean.ezweb.ne.jp, OR
docomo.ne.jp, OR
softbank.ne.jp

How would I solve this problem as it's making our server load skyhigh 24/7.
Additional info about system:
> Debian Linux, latest kernel
> Sendmail (we've tried postfix, exim, with same results)
> Non cPanel system.

recently my mails are not been sent to hotmail and live users from the forum
I just checked by sending a test mail to my hotmail account but the mail wasn't recd. so
I checked the mail queue manager in WHM and the hotmail related mails were not traced.
how I can overcome this problem, I can send mail to hotmail if they are bouncing but when I don't find in the queue , what can I mail about them , when they ask an error id

I have a bare minimal server which I want to move WHMCS over to. However, how do I setup e-mails so I can setill PIPE them into the system? The e-mail server would be hosted on the main server still.

I'm having a problem with mails on my server. I configured csf and ddos deflate to send a mail to "root" when some ip is blocked. I made .forward in /root dir with my mail but I still don't recieve an email when an ip is blocked by csf or ddos deflate
P.S Mails with webmail clients are working fine

Eventhough, I did not setup any signatures. Plesk server with spamguardian running.

One of my e-mail addresses - steve@acme.ie - is regularly marked as spam. My mail server is not blacklisted. My e-mails are always plaintext, and only sometimes have URLs in them.
Looking at my mail server health everything looks ok except for what I assume are reverse DNS entries for my domain. So I'm guessing this is the problem.
So...
1. Do I need to ask my hosting company (I have a dedicated server with the planet) to set up reverse DNS entries for all my domains, or can I do this manually? Note I use my own DNS server, I do not use the hosting company's DNS server.
2. Will it be a problem that all my domains (dublinjobs.ie, acme.ie, etc.) use the same IP?

well we are reseller with some dozens of site...
we use squirell mail for mails for all the sites hosted with us..or the cpanel...
the problem lately is that
our sites mail.............all sites hosted with us are getting hundreds of spams every day..mails of all sites seems similar...
even if we create a new site in our account..a brand new site starts getting hundreds of spam mails..
so it has made things very difficult...
most of mail seems normal with normal names and normal subject like hello...
so it is making things very difficult ..
we feel that ip of server has been targeted by spammers..
