Server is getting spammed
« on: 2017-09-01, 07:18:21 »
Team,

Someone is using our SMTP for sending spam mails, and the failures are coming back to us.

Requesting you to please guide on security measures we need to take on securing the mail server.

You need investigate your website one-by-one for where websites hacked. You can see maldect, maillog and clamd log in 'log manager' to know about send mail issue.

Till you clean up your website, you can add '/home/<user>' for certain users in 'sendmail bans'. With this trick, send from website for certain users will be banned (aka no permit to send mail).

Clamd log was clean only database status check was seen

If Spamdyke is enabled, this isn't the step that should have blocked spamming?

I am trying to Enable Default DNS RBL Servers, but the checkbox always stays unticked.
Screenshot as below.


Could you please suggest steps to protect servers from spamming

Is there any way I can configure SMTP to stop mailing for anonymous mails? Any good configuration I can do for stopping spammer from using our mail route?

Try 'sendmail to bans' for certain client.

Doing that won't ban the entire mailing for that particular client?

Ok this is now added

But is there a way we can block SMTP sending without login credentials?

Look at 'mail log' in 'log manager'.

'Sendmail to bans' only work for sendmail (send in 'mail log'). No impact for submission or smtp.

Inform here what's you set for 'sendmail to bans'.

For your issue, clean your applications (php file and or database) for hack code.

BTW, are using wordpress?.

Can configuring rcpthosts file here help avoiding the current spam attack?

Can you please point me in right direction?

Have added below lines to "/var/qmail/control/rcpthosts" file

Code: [Select]
127.:allow,RELAYCLIENT=""
192.168.1.:allow,RELAYCLIENT=""

Will this help make our server not an open relay client for others?
