Php Script Not Sending Mails To 3rd Party

[hindixp]

HI,

when using a simple php script to send a mail Its only relaying mails to local e-mail addresses. When I used my yahoo, fastmail, gmail account, I received

no mails but when I used a local e-mail address of hosted domain, I

received the mail instantly.

I don't know why is this happening.

 

Any Suggestions ??

Have you tried using the "Trace an Email Address" tool in cPanel?

Perhaps you should submit a help desk ticket so the techs can have a look at this.
