The @IP should not be a problem at all. I sent a mail to over 1,000 servers for a mailling list and i used SMTP auth to authenticate with my SMTP to send it, and it worked fine, EVEN though @IP is added. This includes quite a few french servers.
If it's an ezmlm list, it strips all Received headers before sending the message out, and it handles all bounces (so you won't see them).
