hello..

exim is flooding my server and useing a lot of memory and cpu.
i close him and i removed all the messages on queue and start again exim..
it's again flooding..
i stopped exim again and removed all queue (new queue)

i think some user flooding with sending a lot of message because it's create big new queue after i stopped and removed old quere..

please help:(
 
You need a server administrator to look at your server.
 
if mails are spammed by php script
cat one of the message in your queue, read the header part, determine which domain is causing the problem, kill the script or suspend that user.

if spam by smtp
you should be able to determine it from /var/log/exim/mainlog

good luck
 
cat one of the message in your queue, read the header part

That's a good idea but it will only work if he has a patched version of php.
 
the log is flood with many lines like this:

It seems like someone guessed your admin password and is using it's email account to relay email through your mail server. Change the password with something harder to guess.
