My server hang this morning and I had to reboot the server. After
rebooting I found thousands of .gse and .smd files in the spool
directory and my yesterday log file 29/03/2003 grew to 100Mb where
normally less than 10MB. I went through the previous day log file
28/03/2003 and notice there is a lot of entries belong to a particular
IP address. Could all the queue mail from the previous day. Here is a
snaphot of the log files and the .gse file

There are heaps of entry for [0.0.0.0]connect 65.247.177.24 port 0
errors. Then there are thousands of entries trying to send to @mail.ru

When I open up the .gse file it always contain the
smtp0391.mail.yahoo.com entries 

I've check the SMTP relays and they all looks fine to me. 

Can anyone tell me what's is happening here? I also noticed that
occationally my log file grow by 3-5 times in size but yesterday it
crash my server. 

Anyone's help would be greatly appreciated. Infact this is not my first
time having this problem. 

Regards
Bo Wee
