[Dovecot] lmtp problem with wrong index path

[Dimos Alevizos]

I managed to reproduce the problem, but it required sending 1000 mails 
with multiple recipients.
In every case I checked, the wrong index path is indeed the first RCPT 
TO's in that session.
However it doesn't happen to all other recipients in the session, nor to 
the same one each time.
In any case since the mail get delivered to the correct mbox and you say 
that the errors are unnecessary we can essentially consider it case closed.

I've got another question about the directors though and what you 
mentioned in your earlier mail that we can set mail_nfs_index=no and 
mail_nfs_storage=no.
I've noticed that our directors point to different backends if the user 
logins as "user" vs "user at domain" and as a result there are users ending 
up in more than one server (several of them use just their username in 
one client and the full user at domain in another and vice versa).
Up till now we didn't think much about it because it's not that common.

Our directors have the following config :

userdb {
   driver = static
   args = proxy=y nopassword=y
}


We tried changing that to ldap with the same config you posted but it 
doesn't change anything.
I presume it can be configured and we're just missing something ?

With mbox that of course doesn't work, but looks like instead of failing silently it logs an error. So everything is working as it should, except there are these unnecessary errors logged. I'll see about getting rid of them.
