Hello,

When i send m,ails to other mail account(outside) my mails are marked as spam.

Here is part of msg at the header as it reads from yahoo.

Code:
Received-SPF: none (mta1057.mail.sp2.yahoo.com: domain of mimi@ardhi.go.tz does not designate permitted sender hosts)
How can i solve this problem? Any idea?

Regards
