(Home >> Security Center >> SMTP Restrictions)

Overview

You may want to deny users the ability to bypass your mail server to send mail. This is common practice for spammers.

This feature allows you to configure your server so that the mail transport agent (MTA), Mailman mailing list software, and the root user are the only accounts that are able to connect to remote SMTP servers.

How to manage SMTP restrictions

To modify this setting, perform the following steps:

  • Click Enable to deny users the ability to bypass your mail server to send mail.
  • Click Disable to allow users the ability to bypass your mail server to send mail.
