"java.lang.OutOfMemoryError: unable to create new native thread"
usually means the thread stack space is too large. Interestingly this
is the only thing not in your string below, so it's at the default
(which can be quite large, depending on platform). Basically, the
mailer is queing up a whole laod of threads and they are all taking
too much memory each as stack, hence the error.
Try -Xss128k (work up from there if you get class
java.lang.StackOverflowError instead).
You could try making the heap bigger too (1024MB might just not be enough).
As an aside, did you notice you have -XX:NewSize=64m twice?
