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
Settings for 'stock' qmail-toaster

mail_plugins = $mail_plugins quota plugin/quota = maildir protocols = imap pop3 ssl_cert = </var/qmail/control/servercert.pem ssl_key = </var/qmail/control/servercert.pem
the following will likely be the default at some point
ssl_dh_parameters_length = 2048
namespace { inbox = yes location = prefix =
prefix = INBOX.
Use 'prefix = INBOX.' for Courier-IMAP compatible transparent migration.
This forces all client apps to create subfolders underneath/within
the inbox instead of adjacent to it. It's not necessary to be that way.
FWIW, shubes thinks this setting is annoying/rediculous/retarded.
As a practical example, having no prefix allows mobile users to select
which folders get synchronized. Otherwise their whole mailbox is
synchronized, and they have no way to choose which folders they want sync'd.
separator = . type = private }
