Does not start, caused by missing attribute in Twisted

[Luc Stepniewski]

When trying to start bley, got the following error:

root@proxy:~# service bley restart
 * Restarting intelligent greylisting daemon for Postfix bley /usr/bin/bley:171: Warning: Table 'bley_status' already exists
  dbc.execute(__CREATE_DB_QUERY)
Traceback (most recent call last):
  File "/usr/bin/bley", line 221, in <module>
    bley_start()
  File "/usr/bin/bley", line 184, in bley_start
    twistd.daemonize()
AttributeError: 'module' object has no attribute 'daemonize'

Here is my Python version and Twisted version (from packages):

root@proxy:~# python
Python 2.7.6 (default, Oct 26 2016, 20:30:19)
[GCC 4.8.4] on linux2

You need this patch:
https://github.com/evgeni/bley/commit/fe64c8890d09ccee126680cda7f1b8d1d2369764

Or just a more recent bley.

Could anyone add this patch to the package to have something that works?
