Check your settings under System > Component > Settings > Mail Settings.  Also, be sure your mail server is set up to send mail off-server.  If it's not, you might be getting copies of mail which cannot be sent.

And those mails are all addressed to the same address in the settings?  Do all the headers match?

I've just checked the code.  Forgive me as that's something I wrote and forgot about nearly 7 years ago.  It's remained pretty much untouched since v6.  On some mail setups you, as the sender, will get a copy of each batch message that goes out.  You're getting 1 message now for every 100 addresses being sent to on the list.

The messages need to be addressed to someone so it can't be stopped.  The way they're batched is the message is sent to you and 100 recipients are BCC'ed on it.  Really you should be using an outside service to send these types of messages.  The mail list functionality in our software is deprecated and will be removed in a future version in lieu of integrations with constant contact, mail chimp and icontact.

I have a similar problem using the PHP mail function. SMTP stopped working for some reason a few days ago. I received about 15 copies of the sent email, but on top of that each email had in the TO field the email address of all the customers it was sent to i.e. they weren't BCC'ed. Customers also received emails with other customers' addresses showing. Any idea what's wrong?

Thank you.
