I was looking around my mail server logs a little today and I stumbled across this entry:
I have my SMTP server set so that it will deny all connections that don't give a HELO. So would I be correct to assume that this is someone trying to use my SMTP server to maybe send spam? Or maybe it's just someone who's trying to piggyback off my my server. I know that no one has an account using that provider.
