With our Linux client we got no problems. Opening or sending mails with attachments which was done in a second before the update, took some minutes after the update to kernel 3.2.0-65! Installing the kernel version 3.2.0-64 on our firewall system fixed the problem, also the newer kernel linux-generic-lts-trusty did fix the problem.
