    Hi,

    I think it must be -bd. That starts the daemon. When an incoming call arrives, the daemon forks a copy of itself to accept the incoming message. It will show as the same process command. Try to run "exiwhat" to find out what the processes are actually
    doing. Also check the value of your smtp_accept_max.

    Regards,

    Bright

    Hi Jolo2,

    You can find the value of smtp_accept_max in your exim configuration file.

    Regards,

    You may want to consider running spri from rfxnetworks, it is a nice way to set the nice command for running daemons such as exim and such...

    How long is it running at 99.9%? If you are running Redhat 9, that's fairly common. It just means that at that particular moment, it is demanding that amount of resources at that particular time (which can be a second or 2)

    What was the load? If loads are low, it's nothing to worry about.

    Running something such as this without knowing what you're doing can be hazardous to the health of your server, so this isn't usually the best approach.

    Too many use "top" as a system tool, when it's really not. Top polls the processes at the current time, which can cause problems, because ALL processes take time starting up and processing things. The data from top shouldn't ever be relied on for 100% accuracy.

    That said, there's a few things you can do.
    A> if you're using CPanel, go through WHM mail queue and investigate this. You should be able to pull the person doing the spamming out of there and mail stats.

    B> Adjust your exim configs (/etc/exim.conf).

    C> If you're using mailscanner, set it to run more frequently.
