We use silverstripes email functionality to send users an activation link after registration and to send them reminders (through a DailyTask). Since going live the email behave quite strange. Most of the emails are sent ok, but some (5% of the activation emails) are missing the recipient and some emails are totally blank. I can monitor this because of the bcc_all_emails_to in the config.
In the database the objects are correct. It somehow seems that the email templates are not populate in the right way.
We are using lighttpd with xcache for php acceleration. Could this be the cause for this.
