[hr module] When sending email, it doesn't checks the From Email

Hi,

Under OpenERP 6.1.1 downloaded from openerp.com, module version 6.1.1.1.

If I send an email from the job applicant view, a popup with "Send an email" appears. It asks me to fill the "From" field, but if I don't put a valid email, the email is not sent but OpenERP says it was.

Traceback (most recent call last):
  File "/opt/server/openerp/addons/mail/mail_message.py", line 535, in send
    context=context)
  File "/opt/server/openerp/addons/base/ir/ir_mail_server.py", line 403, in send_email
    assert len(from_rfc2822) == 1, "Malformed 'Return-Path' or 'From' address - it may only contain plain ASCII characters"
AssertionError: Malformed 'Return-Path' or 'From' address - it may only contain plain ASCII characters
