hi
centos 6 with qmail toaster and dovecot 2.2.7 for pop3 and imap
i have a strange issue which happens on all 4 of my servers
for POP3 users -- on any random day ie once in a while users spread across multiple domains will face a problem of outlook re-downloading ALL the emails in the inbox -- not just a few duplicate emails but the entire inbox.
This happens for multiple email users spread across multiple domains sitting in different locations.
i am searching for a solution for the last several months but nothing yet
require help please
my dovecot config file
