Script to list e-mail account that have mail on a server

Hi

On gentoo Linux I'm trying to find out which users have e-mail messages still on server.
We're moving all user/mail account to a new Linux distribution (RedHat) so I need to know which users still have e-mail messages on a server. Yes I know I can look into each users folder and list messages, but if anyone has a script that will seatch through all users mailboxes and list how much e-mail messages each user still has on a server that would be great!
Any ideas or instructions how to do this?
Regards,
Miha

 

I don't have such a script, but I think it should be easy to migrate all email accounts using imapsync: http://www.howtoforge.com/how-to-migrate-mailboxes-between-imap-servers-with-imapsync

 

Thanks! Tried with imapsync, I get error on second server that I want to transfer mail to

Error login: [XXX.XXX.XXX.XXX] with user [[email protected]] auth [CRAM-MD5]: 2 NO [ALERT] Unsupported authentication mechanism.

Any ideas how to solve this?

 

There seems to be something wrong with authentication on the second server? Did you check the mail log?

 

Hi

Running with option --authmech2 LOGIN solved the issue!
