mbox 2 Maildir

[Marc Roos]

I am also migration away from mbox to in my case mdbox. I am not fully 
aware of something that allows you to do this without downtime.

To try to do as much as possible online, I have created an archive 
namespace and am moving the larger >5GB mbox files with old emails to 
that. So when the time is there to do convert active mailboxes, I have 
less to convert. Maybe this is helpful.

Subject: mbox 2 Maildir

Hi,

I am not an professional system admin, but I am running a small debian 
mail server for many years. It is time to migrate from mbox to Maildir.
There is a nice and clean description for doing this without service 
downtime at https://wiki.dovecot.org/Tools/Doveadm/Sync
I have to set per-user config for mailbox type using userdb extra 
fields.

However, I miss some information and I can not find useful info by 
google.

1. The main question: dovecot will know that for some users the mailbox 
format is still mbox, but others already have Maildir. I do not see any 
hint that I should setup postfix/procmail for handling the delivery 
per-user basis. But I think I have to set this, too.

2. I have not learned much about userdb and it seems that dovecot was 
written for and used by experts. I mean that the docs/wiki is not enough 
for me: from the wiki page of userdb it will be for me difficult to 
setup one. Can you suggest some docs for dummies?

Thanks for your help, Tamas

dovecot --version 2.2.27 (c0f36b0)
postfix  3.1.8
procmail v3.23pre 2001/09/13
