[SOLVED] Problem IMAP email syncronization problem

running ubuntu 14.04 LTS server with postfix, dovecot. pop3 email works fine. Now i want to change pop3 to imap. in outlook when i remove pop3 account and create new imap account and import the backup_pop3.pst file it copies the email to server but it does not want to sync so outlook does not work. There are any errory in mail.log or mail.err!
Are there any options to set in the config settings specific for outlook to set for imap to work in outlook?

my postfix main.cf:

On RoundCube it works fine. When I import in outlook a small backup.pst file (200-300MB) it also works fine and there is no problem with syncing. But everything above 300MB just syncs slow even after the first sync when it copies all the email to server.

after increasing this setting in dovecot.conf itworks a bit faster, but i'm not shure what this setting are exactly or what they do!?
service imap-login {
client_limit = 10000
process_limit = 5000
}

 

Is there a way or a command to see what users are connecting/logged to the server with pop3 and what with IMAP or where one can see this?
How to view the mail-server load and resurce usage without munin(is a multiserver setup with 1 publc IP and traffic redirectet with ports so got munin only showing for webserver in ISPConfig)?
How to see who is in fail2ban and how to get him out?

 

Thanks for all the help and info Till! Is there a command to delete duplicate emails out off the /var/vmail/domain/mailbox/Maildir/cur/ folder or at least a way to find duplicates that are made after importing the outlook.pst file?

 

So no way for deleting them directly from the server? Thanks once more.

 

There was really no other problem than outlook. Roundcube webmail, mail on android phones, thunderbird, iPad mail, itd... works fine.
