Hi,
You are processing a too large email. SetMimeHeader mailet is modifying
your email, but fails allocating more resources.
This may be caused to a missing pre-allocation parameter in
ByteArrayOutputStream. This sounds from the stacktrace like a limitation
of the javax implementation. (You might get very long headers on this
mail, I guess)
We had some recent work with javax, and it might be interesting to know
if this limitation is still here.
You get the error on a recurrent bases as James is marking processing as
failed and will re-attend it. You might want to position a
"SizeGreaterThan" matcher to defend against this.
Hope this helps,
Thanks for the report,
Benoit
