Statistic on unsuccessful subscription tries

[Fatalin]

Hello maschoff,
Hello Community,

Is there a way to get a statistic of unsuccessful subscription tries?

- Wrong E-Mail Format
- Blacklist
- Double-Entry

We are using the http://www.mogelmail.de list of "10-minute e-mail addresses" as part of our black list. It would be interesting to know how many people try to subscribe using a "10 minute e-mail address".

Thank you very much.

Best Regards
Markus
