Using the email all users function in back end.

Any ideas why the 704 failed please?

There should be a server error log for each one, unless they don't have email addresses.

Well they used them to register for the form recently. Well about a year ago.

Where would the server error logs be please?

 

[flowerpot132]

Sorry found them.

Eg:

Email to ************** failed: Unable to send mail.8 minutes ago - library/Zend/Mail/Transport/Sendmail.php:137
Delete...
Email to ************** failed: Unable to send mail.10 minutes ago - library/Zend/Mail/Transport/Sendmail.php:137
