Hi

How can I convert all virtual mailboxes from maildir to mdbox? Manually, one by one, working, but I have a lot ...

Virtual users and domains stored in sql database.

Thats what I want:

mail_location = maildir:/var/vmail/%d/%n/Maildir to mail_location = mdbox:/var/vmail/%d/%n/mdbox

Thanks Levi

http://wiki2.dovecot.org/Tools/Dsync

dsync should do it , but be aware from dsync bugs in some versions do heavy testing before doing something live, for many users do i.e with bash script

export your users from sql to a file, or use live query

for i in cat user.lst do dsync ..... done

for avoid acl and quota problems

dsync -o plugin/acl= -o plugin/quota= -u ....

perhaps look at

be aware of, if use zlib plugin all backup mails get compressed too

I've converted around 4-500.000 users from maildir to mdbox by the following on a server configured for using MDBOX as default:

1 - Search for all users with mailMessageStore attribute in LDAP 2 - Convert user to mdbox: dsync -v -u "$username" mirror maildir:"$maildir" + check returncode dsync -v -u "$username" mirror maildir:"$maildir" + check returncode 3 - Delete mailMessageStore attribute from LDAP and add "mailLocation: mdbox:~/mdbox" 4 - pkill -HUP -u dovecot -f dovecot/auth -- to make sure auth cache is updated 5 - doveadm kick "$username" -- on all servers, in case user was logged in.. 6 - Do final sync: dsync -v -u "$username" mirror maildir:"$maildir" 7 - Delete maildir.

Only 26554 users left to convert..
