I maintain a website that is new and on which I have tried to send bulk emails BCC to about 90 emails at a time from a website email that goes through an alias with a .cc extension. Every time I send an email with this email in the Sender line of the module, I get a Support@[domainname].org email that is blank in the body, no Bulk Mail report, and a message is sent out that appears from the website email address and is completely blank in the body. Any ideas what could be wrong?

I figured it may be a problem with DNN interpreting a .cc email alias. It is not very common. So I used a different website email that does not go through that type of an extension in the alias list, and a number of people did receive emails with correct messages in the body, and that also produced a Bulk Mail Report to me. However, I also have a few people saying that they did not receive a correct email at all, just the blank one.
