Hello,

I'm trying to migrate a legacy system to Dovecot in which I need to support mbox format storage with the following parameters:

Inbox is in: /var/spool/mail/%u Additional mail folders are stored in: /var/spool/mail2/%u (i.e. Spam, Sent, Trash, Drafts, etc.)

/var/spool/mail and /var/spool/mail2 are configured with the same permissions. (Read/write/execute user root, Read/write/execute group mail). I've added mail as an additional group in the Dovecot configuration.

# dovecot --version 1.0.10

# 1.0.10: /etc/dovecot.conf ssl_cert_file: /etc/pki/dovecot/certs/dovecot.pem ssl_key_file: /etc/pki/dovecot/private/dovecot.pem login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login first_valid_uid: 100 mail_extra_groups: mail mail_location: mbox:/var/spool/mail2/%u:INBOX=/var/spool/mail/%u:INDEX=MEMORY auth default: passdb: driver: pam userdb: driver: passwd

The problem is what when I run this configuration, I am not able to see any of the contents of /var/spool/mail2. I ran around with this problem for a while and ultimately found that the following fixes it:

cp -Rpfd /var/spool/mail2 /home

Change Dovecot to use /home/mail2/%u instead: # 1.0.10: /etc/dovecot.conf ssl_cert_file: /etc/pki/dovecot/certs/dovecot.pem ssl_key_file: /etc/pki/dovecot/private/dovecot.pem login_dir: /var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login first_valid_uid: 100 mail_extra_groups: mail mail_location: mbox:/home/mail2/%u:INBOX=/var/spool/mail/%u:INDEX=MEMORY auth default: passdb: driver: pam userdb: driver: passwd

Further investigation revealed that no path outside of /home would work for the storage of the mbox directory. Any ideas? Everything seems to work great except for this one (pretty major) issue.

Also, /home, /var, and / are separate filesystems. I'm not sure if that's playing into this or not (doesn't seem like it, since it seems to have no issue storing INBOX in /var/spool/mail).

Thanks,

-Bill
