I now have

default_mail_env = mbox:~/mail:INBOX=:/var/spool/mail/%u

I now getting:

Apr 26 15:55:32 jedrik imap(mclay): open() failed with mbox file : No such file or directory

I tracked down where the error message is getting generated and added some more printing:

In mbox-index.c I added:

int mbox_set_syscall_error(struct mail_index *index, const char *function) { i_assert(function != NULL);

    i_error("index->mailbox_path: %%%s%%", index->mailbox_path);
    i_error("index->dir: %%%s%%", index->dir);
    i_error("index->filepath: %%%s%%", index->filepath);
    i_error("index->control_dir: %%%s%%", index->control_dir);
index_set_error(index, "%s failed with mbox file %s: %m",
		function, index->mailbox_path);
return FALSE;

}

This generates the following output. It seems clear that the initial reading of mbox is read correctly because index->dir and others have values derived from it but for some reason mailbox_path is empty. This is version 0.99.10.4 built with gcc 3.3.2. Here is the bottom of running ./configure:

Any ideas?

Thanks
