 * Out of 1600 something subscribers my Newsletter was only sent to 9! I get the
   following error:
 * > “SMTP Error: Data not accepted.
   > The transmission process was stopped because there was too many errors.
   >  All
   > emails that are not sent ended up in a queue so that you can continue the transmission
   > later. Please verify your settings for sending e-mail and make sure you can
   > send a test of this e-mail. If you previously managed to send out multiple 
   > e-mail, the error may be due to your server’s capabilities.”
 * This is my first multiple e-mail list, so I have not been successful in sending
   out any newsletter yet.
    Test mail ok, but with this notice:
 * > Notice: mail(): Policy restriction in effect. The fifth parameter is disabled
   > on this system in /customers/e/2/c/valet.se/httpd.www/wp-content/plugins/wysija-
   > newsletters/inc/phpmailer/class.phpmailer.php on line 537
 * I am sending from my own website.
 * What can I do?!

 * Solved: it was a conflict with bounced e-mail address.

 * Hi,
 * We’re glad everything is working as expected.
    What was the sending service you
   were using?
