Warning: mail() [function.mail]: Could not execute mail delivery program!

Hi Guys,

I just bought a VPS and i'm facing some problems with it, if i send emails in PHP with my website i get this kinda errors:

I did follow this steps but it wont help: http://www.ehow.com/how_7581793_could-mail-delivery-program-usrsbinsendmail.html

It's just so weird because my script is sending the mails and my users are receiving it (well only 300 of my 1000 users), but i'm still getting this error..
Can someone help me out please?

Kind Regards,

Sebastiaan de Weert

The problem can also be caused by the php script you are using to send the mail, and I truely believe that is the case.

I see you also posted the question on sitedeals (.nl) and people are already trying to help you there. That might be better as this is no Directadmin problem but a script problem. Several good Dutch scripters are present on sitedeals.

Sure. Why not? It's a link to exim. It's installed when exim is installed. All the options shown are standard exim options.
