Look for &#8220;<strong>Max hourly emails per domain<\/strong>&#8220;.\u00a0 It is the maximum number of emails each domain can send out per hour. By default it is set to unlimited which is a high risk. You can click the Radio Button just below it, limit it to the one you want. Click on Save &amp; you are done. Our <a title=\"limit\" href=\"https:\/\/www.milesweb.in\/hosting\/shared-hosting\" target=\"_blank\" rel=\"noopener\">shared hosting plans<\/a> offer <strong>500 emails per domain per hour<\/strong>.<\/p>\n<p>This will limit the emails being sent from somemailaccount@domain.com. But, there are scripts which send emails using nobody@hostname.com OR cPaneluser@domain.com. This is possible using scripts in php, perl etc. To overcome this, you need to enable SMTP Authentication. <strong>SMTP AUTH<\/strong> as the name says, is a method to send emails using authentication mechanism. Email won&#8217;t be sent using a script if it is not authenticated with correct Username &amp; Password.<\/p>\n<p>To enable it, you need to add php mail to disable function in php.ini. Doing this, every user who uses a contact form OR script to send emails, will need to enable SMTP AUTH in the scripts.
