I'd like to implement the virtual plugin so that POP3 users can see emails
in their own inbox and a public namespace. As I understand it, I need to
set "inbox=yes" separately, depending on which service the user is
using.
With passwd-file flat files, this means:
userdb {
args = ... /path/userdb.%s
}
userdb.imap:
set the extra fields for each user userdb_namespace/inbox/inbox=yes
userdb.pop3:
set the extra fields for each user userdb_namespace/virtual/inbox=yes
But without even getting to the virtual namespace part, I'm having
difficulty getting the extra fields setting to work for a regular IMAP user.
Specifically:
If I use the Dovecot default settings of namespace inbox, which includes
inbox=yes, and do NOT include the extra_fields value shown above, then IMAP
users can log in OK.
But if I comment out inbox=yes within namespace inbox, and then add the
extra fields to userdb.imap (as shown above), (and reload doveadm), then the
IMAP user is no longer able to login. Thunderbird displays "Login to
server
... failed." and I get the following in syslog (mail.err):
Aug 1 13:56:13 n6mef-gw dovecot: imap(mefimp at email.n6mef.org): Error: user
mefimp at email.n6mef.org: Initialization failed: namespace configuration
error: Duplicate namespace prefix: ""
Aug 1 13:56:13 n6mef-gw dovecot: imap(mefimp at email.n6mef.org): Error:
Invalid user settings. Refer to server log for more information.
I'm at a loss for what's wrong. Can someone help?
Userdb.imap test entry and doveconf -n below.
Thanks,
Michael
