What Are They Looking For?

For the past few weeks, our pseudo SMTP server has been receiving numerous strange connections that I do not understand. Overall attempts to deliver mail are down, but we are seeing many of these:

1. 70.75.146.190 on port 55628|10:09:08

1. EHLO

1. HELO

1. QUIT

1. Closed.|10:09:08

from many different IP addresses and locations. Obviously it is a BOT Net, but what are they looking for? There is no MAIL FROM: or RCPT TO:, just EHLO, HELO, and QUIT.
