I don't remember what OS you said you're using, but if
the VM is killing processes, that usually means that
you're running out of virtual memory (i.e. RAM + swap).
How much RAM and how much swap do you have configured?
And how much of the swap is in use?

Depending on your OS, you should be able to add more
swap on the fly (e.g. by adding a swap file).  It won't
make things go faster, but at least it will prevent
your processes from being killed.  Of course, it is
better to add more RAM _and_ more swap.  (Adding only
RAM will help in the short run, but it will actually
lower the safety margin that your swap provides.)

I don't think so.  It won't solve the problem, it might
only change the symptom (i.e. rejecting mails, instead
of killing processes which -- in effect -- also results
in rejected mails).
