There didn't seem to be anything out of the ordinary with our email server, so chances are it had something to do with the email service you use. Some email services (cough, Hotmail) do tend to have problems with such emails as membership confirmations.
In any case, I see that you've posted outside this section, which means that the problem is no longer there. Therefore, I shall mark the issue as resolved.
Sorry to bother you again, Ryzen. This time's its just a normal reupload request. You might want to update it first to its v1.02, if you're not too busy. 炎のおっぱい異世界 おっぱいバニー学園
