Hi Richard

Hopefully this will be threaded but I am forced to use Alpine at the 
moment!

netstat output shows

[root at maui:~]$ netstat -pln | egrep ':993|:143'
tcp        0      0 :::993                      :::* 
LISTEN      2515/cyrus-master
tcp        0      0 :::143                      :::* 
LISTEN      2515/cyrus-master

I did check whether cyrus type things were changed from 6.6 to 6.7
but it seems that nothing has been changed

Current (6.7 rpms)
[root at maui:~]$ rpm -qa|grep -i cyrus
cyrus-sasl-lib-2.1.23-15.el6_6.2.x86_64
cyrus-sasl-gssapi-2.1.23-15.el6_6.2.x86_64
cyrus-sasl-2.1.23-15.el6_6.2.x86_64
cyrus-sasl-devel-2.1.23-15.el6_6.2.x86_64
cyrus-imapd-utils-2.3.16-13.el6_6.x86_64
cyrus-imapd-2.3.16-13.el6_6.x86_64
cyrus-sasl-plain-2.1.23-15.el6_6.2.x86_64

I have checked as follows (and the 6.6 and 6.7 repos)
