do LMTP and Quota-status fail, if you symlink them to the imap version?

So this creates the question: For each service, which fields does the userdb need to contain? I can't find that documented anywhere.

For example, for the quota-status service, I presume the following are needed: -- username -- home directory (since mail_location = maildir:~/Maildir) -- any "quota=" overrides in the extra-fields -- nothing else

Is that right?

And I presume userdb.lmtp needs to return: -- username -- home directory (since mail_location = maildir:~/Maildir) -- nothing else

Is that right?

Thanks, Michael

-----Original Message-----

The service specific passwd-file userdb is causing quota-status and lmtp to fail.

Using: userdb { args = ... /etc/dovecot/auth.d/%d/userdb.%s }

I'm getting the following in /var/log/mail.err when I try to send/receive mail:

Aug 1 15:46:57 n6mef-gw dovecot: auth: Error: passwd-file(mefpop@email.n6mef.org): stat(/etc/dovecot/auth.d/email.n6mef.org/userdb.quota-status) failed: Address family not supported by protocol Aug 1 15:47:08 n6mef-gw dovecot: auth: Error: passwd-file(mefpop@email.n6mef.org): stat(/etc/dovecot/auth.d/email.n6mef.org/userdb.lmtp) failed: Address family not supported by protocol

I don't have a userdb.quota-status or userdb.lmtp.

Is there something else that needs to be in the configuration to prevent these services from needing their own userdb?

Thanks, Michael

I didn't try a symlink because I intend to have separate users in userdb.pop3 and userdb.imap so I can control who has imap access. To allow the two user lists to be independent, I made a unique union of the pop3 and imap userdbs and used that for quota-status and lmtp.

BTW: your posted conf does not contain the virtual plugin and its namespace.

Correct. As I put in the previous email, I didn't get to that point. First, I just commented out the "inbox=yes" declaration from "namespace inbox {}" and then added it to the userdb.imap extra-fields but got an error.

How embarrassing. I just discovered a syntax error. I was using: userdb_namespace=/namespace/inbox/inbox=yes Instead of: userdb_namespace/inbox/inbox=yes

Now that's working.

BTW, it turns out that both quota-status and lmtp need to see the value of inbox=. So I guess all of the userdb.%s files will include userdb_namespace/inbox/inbox=yes, except for userdb.pop3 which will use userdb_namespace/virtual/inbox=yes.

Next step is to configure the extra namespaces.

Thanks for your help so far Steffen.
