TOPIC: E-mail registrants-function, log?

Is there a way to check that the e-mail registrants-e-mails have gone trough to everyone and if not, to whom it did go to? The server we are using seems to have a lousy mysql response time (BEWARE OF SITEGROUND!) which causes continuous problems and for instance this e-mail function returns an "You have chosen to open index.php..."-message. I am afraid that the mail does not reach everyone before this error. Any logs etcetera anywhere from DT Registers side?

Thanks, Ben

Or perhaps the ability to send a BCC to a separate email account. Obviously a special one only for this purpose.

This type of function does not presently exist. The email registrants function is pretty simple at this point. We are hoping to expand with these type of features in an upcoming release. I can see how this would be helpful.
