Hi!

I have a Zimbra 8 setup. Everything works pretty smooth, but some of users started to complain that they are receiving SPAM e-mails from their own address.
Looked at headers and found out that there is no record of SPF check.
So the question is - does Zimbra 8 have SPF check enabled by default, or i have to enable/install it some how?!

regards,
Martins
