STOP spam mail to server

[labpros]

Is there any reliable way to stop the spammers? This is a serious problem because its difficult to understand when spammers connect to your server and send thousands or million of mails from your server and finally the providers stops your mail services or at least the big mail providers doesn't deliver your mail server messages.

Find out with command 'cat /var/log/maillog|grep PWD|tail -10' (change 10 to 100 if want more) and you will see like:

> cat /var/log/maillog|grep PWD|tail -10

Apr 14 14:07:37 oln3 root: sendmail: CALLER="php-fpm: pool devel" PWD="/home/devel/forum.mratwork.com" BAN="no"
Apr 14 14:46:10 oln3 root: sendmail: CALLER="php-fpm: pool devel" PWD="/home/devel/forum.mratwork.com" BAN="no"
Apr 14 15:59:23 oln3 root: sendmail: CALLER="php-fpm: pool devel" PWD="/home/devel/forum.mratwork.com" BAN="no"
Apr 14 18:14:57 oln3 root: sendmail: CALLER="php-fpm: pool devel" PWD="/home/devel/mratwork.com/wp-admin" BAN="no"

With this example, if you think website with '/home/devel/forum.mratwork.com' as spammer, and then add '/home/devel/forum.mratwork.com' in '/var/qmail/control/badsendmailfrom' file.

NOTE: PWD = 'print working directory' and this context is where sendmail came from.

Thanks Mustafa, But how can i automate a procedure for stop spamming? Does exists any tool?

In your application, use 'php mail()' instead 'smtp' and then add PWD value in '/var/qmail/control/badsendmailfrom' where you think spam came from.
