Probably not. It just means the other end abruptly closed the connection
without doing a QUIT first.
I've also noticed quite a few servers that have clients attached sitting
doing nothing. You'll see "ps" listings like this (on Linux, anyway):
root 22028 0.0 0.1 [...] sendmail: MTA: server [x.y.z.w] cmd read
Some of these processes stick around for a long time and can cause a
DoS by using up memory. I set confTO_COMMAND to 3m in my config files;
the default is 1h. Haven't had a problem yet.
