a customer sent a mail with attachement to about 30-40 addresses via sunrise smtp. all of this 30-40 receipients keep getting this mail thousand times since yesterday. sender email is info@vsmwh.ch.
sunrise support told the customer that it is his problem and is not willing to check the situation :)
the problem turned out to be the same like in the following swinog post: http://lists.swinog.ch/public/swinog/2005-April/000216.html
two receipients of the mass mail used probably pickup services, which forward the mails to all receipients in the To: header and kept sending each other the same mail, including all others in the To: header.
therefore, stopping one of the pickup services stops the loop.
so better use Bcc: or tell your customers todo so :)
thanks to sunrise abuse desk for cooperation
