At first glance they look like probes scanning your system. SpamFilter will log the fact that a connection is being disconnected for some reason. Most of the ones in your log appear to be disconnecting themselves, which is typical of probes.

Here is an exaqmple of a "Probe".  I have a monitor that makes a connection and if it gets the banner, it disconnects with a "Pass" to the monitor system.  This is "Normal"
