Hello,
I stumbled across a 5-year-old post on the dovecot list about changing the dovecot hierarchy separator to enable shared mailboxes (http://www.dovecot.org/list/dovecot/2011-January/056201.html <http://www.dovecot.org/list/dovecot/2011-January/056201.html>). At the moment I’m stuck in a pretty similar situation. Migrated from courier to dovecot 2 years ago and preserved the dot-separator. Because I’m using the e-mail adress as a username, the dots for folder separation and the dots in the email adresses getting messed up -
I do have a pretty small mailserver with about 150 accounts. The Maildir filestructur of a typical mail account looks like this: drwx------ 2 vmail vmail 4096 Oct 10 20:02 cur drwx------ 5 vmail vmail 4096 Oct 3 07:48 .Daten.Administration drwx------ 5 vmail vmail 4096 Oct 3 09:51 .Daten.Anfragen, Werbung drwx------ 5 vmail vmail 4096 Oct 3 08:02 .Daten drwx------ 5 vmail vmail 4096 Oct 6 09:57 .Daten.Intern drwx------ 5 vmail vmail 4096 Oct 3 08:03 .Daten.Intern.Fahrzeuge drwx------ 5 vmail vmail 4096 Oct 6 12:57 .Daten.Intern.Infos, FileMaker etc drwx------ 5 vmail vmail 4096 Oct 3 09:19 .Daten.Intern.Sonstiges drwx------ 5 vmail vmail 4096 Oct 3 07:47 .Daten.Kunden drwx------ 5 vmail vmail 4096 Sep 16 08:29 .Daten.Lieferanten drwx------ 5 vmail vmail 4096 Oct 3 08:28 .Daten.Marketing drwx------ 2 vmail vmail 4096 Oct 10 20:02 new drwx------ 5 vmail vmail 4096 Oct 10 18:00 .Sent drwx------ 5 vmail vmail 4096 Oct 10 18:00 .Spam drwx------ 5 vmail vmail 4096 Oct 10 18:00 .Trash
When changing the separator in my inbox namespace the documentation mentions that the filestructur doesn’t change. This means I will get the same problems when using shared boxes with email adresses as usernames. I definitly need to change to maildir:~/Maildir:LAYOUT=fs When changing to LAYOUT=fs i need to convert all the mailboxes manually, is that correct? Is dsync is the way to go? Or is it better to leave the separator and change to a different username schema (without dots in it) and advise the clients to change their credentials?
I know there are people out there who successfully converted this - but I can’f find that many information about this subject.
