email from my domain is listed as spam in YahooMail

How to solve it?

[dipta]

When I sent mail from my domain Example.com to my YahooMail (just for testing), I found that my email was sent to spam box, I have to check the "This is not Spam" option from my YahooMail before I could put it in my inbox.

Do anyone have solution for my problem? How to make my email from my domain to my friends' YahooMail could be put in their inbox, not spambox so they would recognize my email?

thx a lot

Usually adding SPF records for your domain helps with Yahoo!'s spam filters.

I have the same problem with <SNIP> my domain when I tried using a php script to send mail.

@bakedjake: Would you please describe more detail on the steps to add SPF records to the domain. I'm new. Much appreciate your answer.

The defacto resource for SPF is here: [openspf.org...]

You'll find a 5 minute setup wizard for adding SPF records to domains and utilities to test those records.

Note: If you don't manage your own DNS servers, you'll likely have to get your ISP involved.
