Installing DOS-Deflate is so simple.

Informations is as follows :-

When you run this Perl script it will then run an netstat command check how many times each IP is connected & if there are more then the number of connections you specified then it will automatically run a command in APF for the IP to be banned,

Properly Rejected Invalid Emails

Just read the method given below to resolve this issue :-

Mail queue fill up with bounce messages to non-existant spammer email addresses, By default. If an email comes into your server addressed to an invalid recipient, Exim will accept the message from the delivering agent, and then generate a return email to them explaining that the address is invalid, With this little tweak, you can make exim tell the delivering agent,Tthat address is invalid at the time the message is being delivered.

********************************************************************

Method <1>

. Open WHM and click on Exim Configuration Editor

. Click on the Switch to Advanced Mode button.

. Scroll down until you see the section on ACL's. You'll see three boxes. In the middle box, locate the section that reads - See Section A:

--------------------------------------------------------------------------------------------

Method <2> Recommended

. Login into SSH and su to root.

. pico /etc/exim.conf

. Ctrl + W and type in: accept  domains , Notice the two spaces. Look for something like this below.

Section A :-

accept  domains = +local_domains

accept  domains = +relay_domains

accept  hosts = +relay_hosts

accept  condition = ${perl{checkrelayhost}{$sender_host_address}}

Between

accept domains = +local_domains

&

accept domains = +relay_domains

add the following:

endpass

message = unknown user

verify = recipient

Make sure each line lines up,You might need to add two spaces before each line, The final section will look like this. :-

accept domains = +local_domains

endpass

message = unknown user

verify = recipient

accept domains = +relay_domains

accept hosts = +relay_hosts

accept condition = ${perl{checkrelayhost}{$sender_host_address}}

Scroll all the way to the bottom and click on Save.

THATS IT YOU DONE 

How to register a domain with using extra IPS

Let's get started with following simple steps :-

1 >

       Login to your registrar panel (Godaddy, Enom, etc..).

2 > 

      Select the domain you want to use & find where you can 'Register New DNS',

3 >

      Put in ns1.yourdomain.com and ns2.yourdomain.com in the respective fields.

4 >

      Put in the IP addresses [either yours or the ones provided to you by your host]

5 >

      Hit the save or submit button.

    ** NOTE:- If you are a regular reseller the rest is done by your host on their end so notify them that you            .         have done your part, If you run a dedicated server, read on.

6 >

      Login to your WHM panel as "root",

7 >

      Go to 'Reseller Center', select 'mydomain.com'. Click on the 'Edit Domains/Privilages' icon.

8 >

      When the page loads scroll down & put in the new nameservers, in this case ns1.mydomain.com &

How to Catch spammers on C-panel

**Just follow given steps :-

<Follow the steps given below to catch Spammers sending mails from scripts ( nobody emails )> :-

1> Edit /etc/exim.conf

 ------------------------------------------------------------------------

2>On the second line add :-

log_selector = +address_rewrite +all_parents +arguments +connection_reject +delay_delivery +delivery_size +dnslist_defer +incoming_interface +incoming_port +lost_incoming_connection +queue_run +received_sender +received_recipients +retry_defer +sender_on_delivery +size_reject +skip_delivery +smtp_confirmation +smtp_connection +smtp_protocol_error +smtp_syntax_error +subject +tls_cipher +tls_peerdn \

Make sure all that comes on a single line,

 ------------------------------------------------------------------------

3>Save and exit,

 ------------------------------------------------------------------------ 

4>Restart Exim,

A keep a watch on /var/log/exim_mainlog as you should be able to trace path to directory from which the spammer(s) is / are spamming,

 ------------------------------------------------------------------------

**If the spammer is not spamming using formmail scripts then go through following steps :-

1]> Get the message ID from the header of the spam, It should be in format like 1DWJj4-00042i-74 ( this is the most important step else all thats given below is crap ).

2 ]> grep exim_mainlog with the message ID, ( Ex : grep 1DWJj4-00042i-74 /var/log/exim_mainlog ).

3 ]> Check the time on which the spam was sent and also check all that is shown after grep,

4 ]> If you find out the domain name or path of the scripts from exim_mainlog then go ahead & suspend the spammer, else proceed to step 5.

5 ]> Use this message ID to check the original message or bounced message in /var/spool/exim/input/. You should see 2 files there, one with -D at end & one with -H at the end, 

( Ex : /var/spool/exim/input/4/1DWJj4-00042i-74-D & /var/spool/exim/input/4/1DWJj4-00042i-74-H ) This 2 files will have all the information that was sent in the spam message & if it was sent using mailing list then you will catch the username of spammer in auth_sender part of this files, If it shows nobody then its your bad luck Proceed to step 6.

6 ]> If exim_mainlog shows the spams originating from /tmp of the server & check the file in /tmp of the server. wner of the file will be seen as nobody:nobody, Take down the time of creation of file. This time is what we need to find out who uploaded the script, You will need to convert this time into the time format of /usr/local/apache/logs/error_log & then in the format of the domlogs located at /usr/local/apache/domlogs/*

7 ]> for file in /usr/local/apache/domlogs/*; do cat $file |grep “example”; done; ( you cannot do direct grep for the query here as it will give error that the arguement list is too long ).

8 ]> If the results in step (2) have shown some domain name or some username in common as sender of the spam but now you dont see that domain name on the server then check /var/cpanel/accounting.log to see if that account has been terminated from the server ( Ex : grep ebayspammer.com /var/cpanel/accounting.log ).

All that we need to know is importance of /var/log/exim_mainlog, /var/log/formmail.log, /usr/local/apache/logs/error_log, /usr/local/apache/domlogs/*,

/var/spool/exim/input/*/* and the files uploaded in /tmp of the server, Major spamming issues are caught using the time of sending the spam,You will need to work on your own when you get across such issue & use your logic to convert the time of sending the spams to the time format of respective log files I mentioned above,
