Hi,
This is regarding updating dovecot.index.cache.
I have few backup ids configured. these are used only when old mail
needs to be retrieved.
usually these mailboxes contains more then 9,000 mails.
while login to webmail, imap consumption is high, which creates
performance related issues for regular mailboxes.
to resolve this i have to move heavy mailbox to dedicated server.
before doing that, I wanted to confirm if there any way to update
dovecot.index.cache even if user is not checking his / her mails.
kindly confirm, & provide direction to implement same.
Following is the mailserver related details
Qmail with Vpopmail 5.4.24
Dovecot-1.1.4
dovecot -n

type: private
prefix: INBOX.
