Every now and then our customers computers are hacked and their passwords used to send out Spam email.

Is there any methods to stop this? I heard somebody say that stopping Nobody emails will help, but doesn't that mean that PHP scripts that send emails will then not work.

Hello :)

You mentioned that the home computers of the email users are hacked, but you also referenced PHP scripts. Could you elaborate on how the SPAM emails are sent out?

Thank you.

Some of my sites use PHP mail to send out things like enquiry forms and alerts. I'm concerned if I stop nobody emails, that my scripts will stop working for genuine email Alerts from PHP which are also nobody?

The emails are being sent out using pop3 or IMAP due to account details being found by viruses and hackers. So a hacked computer will have the username and password compromised. It happens about once a month, but we have about 400 accounts across 3 servers so quite rare.

Hello,

The php mail() function has a "5th parameter" which should be used. More information on how to use it can be found here.
