I was using straight php mail and went to the spam folder.

I thought if I used SMTP, it'd avoid this, yet it's still going to spam folder on yahoo....

Can anyone help?

There are many factors when calculating a probability of spam.

• Reverse DNS is important.
• SPF is not very important but can hurt if configured incorrectly.
• Look at the return-path in your email headers. 'nobody' in many cases and this is also bad for spam filters.
• Your IP address of server can also be an issue.
