Greetings!
Thank you for pointing out this issue, I would like to bring to attention that our services on kocerroxy.com are fully secure and we have been running without any breach. This leak was caused by a third party software called Mailgun.com which we were using for mails. We have contacted them already and working towards a fix for it, alternatively we might switch services because of this issue. We would like to apologize on their behalf for this, we will file a compliant (for breach of privacy) also against them for causing this inconvenience.
Thanks and Regards.
Well obvisouly here is your first breach, it doesn't change if it's you directly or a third party service who leak it, now it's done.
What make me angry about your explanation is that you put the blame on mailgun.com, but that mean you didn't test it before hand. You straight use a new tool without even check that's it fullfill your needs.
You should apologies for using them, and not them to be bad ... Because they didn't force you to use them
