Hi All,

I've been receiving syn_sent on my smtp from an unknown ip which was
causing my sendmail to slow down, I do lsof and found these strange
logs:
-----------
sendmail 24207 root 3r DOOR 0xf6120e58 (FA:->0xf5df6728)

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

sendmail 24056 root 6w VCHR 21,0 0t0 40929
/devices/pseudo/log@0:conslog->LOG
--------------

Am i being hacked or something?

Thanks.
