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?

Code:
This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its

recipients. This is a permanent error. The following address(es) failed:


[email protected]

host somedomain.com [ip1]

SMTP error from remote mail server after RCPT

TO:<[email protected]>:

550 SPF: ip2 is not allowed to send mail from mydomain.com

[email protected]

host mail.anotherdomain [ip3]

SMTP error from remote mail server after MAIL
