The log file now shows:
---
Aug  4 19:10:10 rezclick dovecot: IMAP(john): 
fchown(/home/john/.imap/INBOX/dovecot.index.tmp, -1, 12(mail)) failed: 
Operation not permitted (egid=509(johngrp), group based on 
/var/spool/mail/john)
---

/var/spool/mail/john has a group of "mail", whereas the home directory has 
their own "group". In 1.1.x we did not get these errors. Is this a fix in 
1.2? I assume we have to make the group match from their home dir and 
/var/spool/mail to get rid of the error? Any downside to allowing this 
error to continue? Thanks.
