Chandran, Use 'doveconf -n' (NOT 'doveconf -d') which will show all the settings with NON-DEFAULT values.
Dovecot operates off of the configuration files. You do NOT, or most likely shouldn't, have to reinstall Dovecot. I'll bet that when you run 'doveconf -n' you'll most likely see the current setting from local.conf. Eric On 7/23/2015 9:14 PM, Chandran Manikandan wrote: > Dear Eric, > Thanks for your help.
