SMTP harrasment by nie2.infomail.es?

Hi,

Over the months I get burst of SMTP attempts from nie2.infomail.es that seem to indicate a broken SMTP server.

I reject email from them ever since complaints about spam were bounced as critical users like postmaster were not present.

However them seem to ignore the SMTP specs and resend messages for a period untill they give up. As shown in a sample of my log for the last 60 minutes alone:
