Hello, we just start moving a large number of mailboxes to a new dovecot server with dovecot 2.0.9 (from CentOS) and sdbox as mailbox type. We use imapsync so there is no issue with mailbox type conversion. However, in test runs I noted that some mail folders,e.g. with dots in them, could not be transferred; dovecot says
Couldn't create folder [7.8) Personnel] from [7.8) Personnel]: 106 NO Character not allowed in mailbox name: '.'
We have the separator "/" defined for our only namespace so the dot should not be an issue!? I tried to use listescape but either the plugin is not loading (how can I verify this?) or it does not escape the dot in the mailbox name. The listescape settings are the defaults:
namespace { separator = / (...) }
mail_plugins = $mail_plugins listescape
plugin { listescape_char = "\\" }
What am I doing wrong? How can I make dots in mailboxes possible?
Best regards, Jakob Curdes
