(I'm beginning to feel like a parrot saying this, but...) If you care about why it might help, read this email thread: http://docs.FreeBSD.org/cgi/mid.cgi?1850411724.1687820.1395621539316.JavaMail.root If it happens to help, please email again, since there are probably better ways to fix the problem than disabling TSO.
