One issue I see here is that the original howto was written for CentOS-5 
with dovecot 1.x.

The OP here is clearly using CentOS-6, which uses dovecot 2.x and no 
surprises for guessing that there are a few incompatibilities between 
the config files for dovecot 1 and 2.

Personally, I'd suggest forking the original article and maintaining 
separate versions for CentOS-5 and CentOS-6, or have separate sections 
within the article for CentOS-5 and CentOS-6 where they differ.

To the best of my knowledge this list never did agree a mechanism for 
handling documentation differences between product versions. The danger 
is that if we keep editing changes for CentOS-6 into docs for CentOS-5 
we will end up with broken useless docs.

How do others feel this type of situation should best be handled?
