Subject: [plug] SYN_SENT on smtp


> sendmail  24057     root   11u  inet 0xf6f450c8  0t0   TCP \
> myserver:51869->203.190.83.6:smtp (SYN_SENT)

a SYN_SENT is where a client (in this case is your smtp server) is sending a
SYN packet to the destination server in order to establish a connection...
furthermore, this is the first part of a three-way handshake of the tcp
protocol... unfortunately, the destination server is not responding the
SYN-ACK packet back to the client which the client is still in the SYN_SENT
state until it will turn into CLOSE state when the timer expired...

fooler.
