Hi,
We are having huge problems with one of your sites running on Silverstripe.
It seems SS intermittently screws up outgoing mail-headers.
I can't discover any regularity in the problem , but if I try to send out a mail from the website, +/- 3 out of 10 times it will mangle the mailheaders by replacing the mail-subject , to , cc and bcc values with the value I set for the "from" address.
This happens both in our site as well as in the newsletter module. Sending a newsletter to 1000 people , will result in around 200 to 300 people not receiving it.
Trying to find the problem :
- We checked our mail-logs, but the correct "TO" address never reached our mailserver. So it is not a delivery problem.
- We cannot find any logic behind SS's behaviour. It mangles different addresses on every run (tested that in our mailing-list).
- The intervals are completely random...
Here is a part of the list of outgoing mails that the newsletter produced. Wherever you see "news@ourdomain.com" , the mail never got send to the actual recipient and the subject,to and cc field were replaced by "news@ourdomain.com".
The body of the (personalized) mail was correct and had the correct values (recipients name , email-address etc. etc.).
To: news@ourdomain.com
To: news@ourdomain.com
To: news@ourdomain.com
To: xxx@gmail.com
To: xxxx@hotmail.com
To: xxx@live.nl
To: xxxx@hotmail.com
To: xxxx@g-vang.dk
To: xxxx@gmail.com
To: xxxx@hotmail.com
To: xxxx@hotmail.com
To: news@ourdomain.com
To: news@ourdomain.com
To: @hotmail.com
To: xxxx@hotmail.com
Can anyone confirm this odd behaviour ?
