something strange is going on with my Magento install. Everything with the emails used to work fine, but now I have these messages in my exception.log:
2015-05-11T10:00:02+00:00 ERR (3):

This is written to the log files every 5 minutes so I guess it must be the cronjob trying to send out mail and failing.
I tried tracking the problem and it was caused by this function in Template.php to return false:
$this->isValidForSend()
So following this advice I added this line to the function to figure out why it would return false. It just writes the results of isValidForSend to an email.log file.
Mage::Log(var_export(!Mage::getStoreConfigFlag('system/smtp/disable'),true).';'.var_export($this->getSenderName(),true).';'.var_export($this->getSenderEmail(),true).';'.var_export($this->getTemplateSubject(),true),null,'email.log');
The results from email.log:
2015-05-11T08:35:02+00:00 DEBUG (7): true;'MACHIMA';'info@mysite.de';NULL
2015-05-11T08:40:02+00:00 DEBUG (7): true;'MACHIMA';'info@mysite.de';NULL
2015-05-11T08:45:02+00:00 DEBUG (7): true;'MACHIMA';'info@mysite.de';NULL
2015-05-11T08:50:02+00:00 DEBUG (7): true;'MACHIMA';'info@mysite.de';NULL
So everything seems to be ok, just the last NULL value which is returned by
$this->getTemplateSubject()
causes the function to fail.
I checked the configuration about 10 times and don't find any emails that are being sent out and are missing a subject.
My thought now is that maybe there is an email stuck in a queque Magento keeps trying to send out every 5 minutes.
Is there a way to track down where this is coming from?
Thanks

This is because one of your email template file is missing with subject. It would be good if you specify default subject to every email-template which you are using. You can specify subject in an email template like this :
File :
app\locale\{en_US}\template\email\your-mail-template.phtmlI hope this will resolve your issue.
