Hello,
I get a problem when sending email with the newsletter module. I strongly suspect that the problem is at hosting level, but still you might point me to some setting to bypass the problem.
So I have setup my newsletter on www.cs-acer.ch as being sent by no-reply@cs-acer.ch.
The email does exist, I can read its mail.
So... sending email... and in the no-reply inbox, I find this email below.

The reason being
"Mail sent by user nobody being discarded "
the header gives a correct From field
"From: no-reply@cs-acer.ch"

But reading :
"Received: from nobody by server4.requestdns.com with local (Exim 4.69)
(envelope-from <no-reply@cs-acer.ch>)"

Is there a place where I can play with the received from nobody? Is it a SMPTauthentication that is missing. If yes, where to set it up?

Many thanks in advance,

Eric Chappuis

I checked in my WHM and don't have an option for "Tweak Settings" ... still confused.

I found this POST http://www.vbulletin.com/forum/showthread.php?p=1437856 discussing a similar problem with VBulletin. In there it was a 'server issue' with the configuration and the solutions was (according to the forum)

"So for anyone with a similar problem. By using SMTP for email, I have been able to solve this problem. "

So the question is, how do I get SilverStripe to use SMTP for email functions?

I was able to use this PhPMailer as a work around.
