Hello List,

I am in the process of building a new mail system here. I am hoping to eventually migrate my users from mbox storage to maildir. They have been using mbox forever and would rather get used to maildir slowly.

So I have come upon the idea of using namespaces to provide the different mailstores. Since this isn't available in the current stable, or at least I could not figure out how to do it, I have been working with 1.0-test68 since it provides the ability to configure things with the namespaces.

But I am seeing an error pop up in my maillog file when exiting the client, it is:

May 3 08:11:41 tbox dovecot: IMAP(sub4000): file mbox-sync.c: line 1371 (mbox_sync_do): assertion failed: (sync_ctx->mbox->mbox_sync_dirty) May 3 08:11:41 tbox dovecot: child 12717 (imap) killed with signal 6

Wasn't sure if it is a code bug or if it is how I have the namespace entries setup. In my dovecot.conf file I have:

namespace private { separator = / inbox = yes # prefix = "#mbox/" location = mbox:~/Mail/:INBOX=/var/mail/%u } namespace private { separator = / prefix = md/ location = maildir:~/Maildir } namespace private { separator = / prefix = mail/ hidden = yes } namespace private { separator = / prefix = ~/mail/ hidden = yes } namespace private { separator = / prefix = ~%u/mail/ hidden = yes }

All seems to work except the message showing up in the logs.

My goal/setup is to provide:

1. mbox delivery in the mailspool(/var/mail) from sendmail
2. access to existing ~/Mail/ mbox storage.
3. ability to begin setting up / migrating to maildir in ~/Maildir

Is my namespace config above overkill / borken / wrong?

Ideas / suggestions on this would be greatly appreciated.

Environment:

Server to be: RedHat AS EL4 Clients: Thunderbird, Evolution, mutt, pine, mailreader on OS/X.

TIA
