Php Newsletter Mail Sending Problem PHP newsletter

Hi,
Why can not send emails Gmail, Yahoo, Hotmail, etc through PHP Newsletter. Mail seems to send (no error message and PHPlist reports it was sent successfully) but recipients never get it and it doesn't show up in statistics. But it works fine when i sent a mail to the same domain (like email@mydomain.com) where i installed the PHPlist.

If you type a gmail/yahoo email in the subscription, then you will not get any mails even confirmation mail.

I have tried many PHP newsletter scripts but i can not sent emails to Gmail, Yahoo, Hotmail, etc. It works only with the same domain (like email@mydomain.com)

Is there anything to do with settings from the control panel.

Thx,
Wallace

if you have your own server check the settings of your whm. there should be an option like "prevent the user from sending out mail to remote addresses" just clear that option and it will work. if the server is not your own you can ask from your provider too see if this option is enabled or not. another solution which you can try is to add a "-r" to the end of the sender e-mail (the e-mail which sends main letters) so your function will be something like this mail(To,Subject,Content,From,"-r from") this sometimes help to send to yahoo and gmail using phplist. if these solutions disn't work you can ask for help from phplist developers in their forum and there is also a complete list of issues that may happen in installing this script which you can see.
