Hi! Some people in my company can't send mails to certain email addresses, they're receiving the next message. I'm absolutely new to this, any ideas?

  550 SPF: ip2 is not allowed to send mail from mydomain.com
  You need to add ip2 into the SPF record within the "Authentication" area in the cpanel account for the domain. You add where it says "Additional IP Address blocks for your domains".

  Hello, Yes, as mentioned, you can authorize those IP addresses in the SPF record for your domain name. The "Authentication" option is documented at: Authentication - Documentation - cPanel Documentation Thank you.
