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
--------------

prior to this, there was a malicious attack on my smtp via a server that
was allowed for relay that cause smtp service to crash. So I closed the
service and limit my concurrent smtp access to 12, but the SYN_SENT
continue to ruin the service. 

Looks like there's a file on my server that's running this. If so, how
will I know the location of the file? 
 

Thanks.
