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@email.n6mef.org): Error: user mefimp@email.n6mef.org: Initialization failed: namespace configuration error: Duplicate namespace prefix: "" Aug 1 13:56:13 n6mef-gw dovecot: imap(mefimp@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
