Help getting CommandByEmail working

I installed, the RT-Extension-CommandByMail-0.06. on RT version 3.6.3.
I have the following in the RT_SiteConfig.pm:

"
Set($LogDir, ‘/opt/rt3/var/log’);
Set($LogToFileNamed , “rt.log”); #log to rt.log
@MailPlugins = qw(Auth::MailFrom Filter::TakeAction);
1;

"

The email sent to RT is as follows:

FROM: john.doe@anycompany.com (has rights to reply and comment
to tickets)
TO: testqueue@rttest.vzbi.com
SUBJECT: [vzbi.com #51252] Test Ticket
CF.{Status of the Issue}: Research

RESULTS:

The email gets added in ticket #51252 as correspondence, but the Custom
Field by the name of ‘Status of the Issue’ does not get the value of
’Research’

any help will be appreciated.
