Memory usage of mailscanner and mailwatch

[kfliong]

Hi all,

I just learned a new command "top".

 From this command, you can see usage of resources on your system.

I found out that mailscanner and mysql (possibly used by mailwatch) are
using a lot of memory.

How come there are so many copy of MailScanner running? Is it that each of
the MailScanner process is processing one email? That means that at
instance my system is processing 6 emails, right?

Also, notice that mysqld is also running a few of itself. Could it be
mailwatch? I am not blaming mailwatch or anything, just curious to know.

Thanks in advance.
