Recently I've made the post about "double homedir" problem, but I couldn't recreate it later. Here're the exact steps to make it happen (configuration is at the bottom):

1. set configuration as below with passwd-files
2. clean testms dir (not necessary though)
3. reload dovecot (HUP is enough)
4. access the server with any client using testms user (make sure no other user accesses server before you)

• on the first access, dovecot will create /home/vmail/ppgk.com.pl/testms/Maildir under /home/vmail/ppgk.com.pl/testms/
• on every next access, dovecot will access (and create if it doesn't exist) proper Maildir under "single" home path

Situation will repeat itself, if dovecot is reloaded (or killed and restarted). It happens to both imap and pop3.

Note, that the a single access seems to be enough to "fix" the problem to all the other users in passwd-file, should there be any.

The problem seems to be created by chroot specification in passwd-file & static (and possibly when other dbs are used).

On the first access, dovecot attempts to recreate whole /home/vmail.... directory structure *after* chrooting to the homedir (or without taking earlier chroot into account), at least that's how it looks from ktrace.

If I moved /./ to the left by one subdir, dovecot would attempt to do it under root owned /home/vmail/ppgk.com.pl/ and fail in the process. And so on.

Tilde is another problem - if in dovecot.userdb I change -

maildir:~/Maildir: to mbox:~/Mail:INBOX=~/inbox:

• then single '~' directory will be created under /home/vmail/ppgk.com.pl/testms/, along the inbox file and Mail dir.

If INBOX, CONTROL and/or INDEX is specified explicitely in maildir case, '~' won't be created. That leads to the questiom - is tilde allowed in INBOX under mbox storage at all ?

I can't check '~' in INBOX/mbox case for system accounts atm though.

If you need any more info (like ktrace), let me know.

Configuration:

openbsd 3.9, i386, dovecot 1.0-rc27 (no post rc27 diffs)
