Hi, I am doing some tests with dovecot to replace cyrusimapd, but after the most simple configuration I am getting some strange errors on log.
This is the output of dovecot -n: #davecot -n disable_plaintext_auth = no ( just for testing ) first_valid_uid = 1000 mail_location = mbox:/var/spool/mail/%n mail_privileged_group = mail mbox_write_locks = fcntl namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } protocols = imap lmtp ssl_cert =
I have also chmod a+rwxt on /var/spool/mail and set.
Now here is the strange behavior.
I have 2 users created, user1 and user2. At first , there are no files on /var/spool/mail as expected.
Now I send one email to user1@mydomain and I can receive just fine and there are no errors on logs.

Now I send one email to user2@mydomain and I can receive just fine and there are no errors on logs.

The problem starts if I send one email to user1 AND user2 ( user2 can be in TO or CC )

Although I can receive the email, there's an ERROR log in maillog. It appears user1 wants to open the user2 index file. Any ideas why ?
Thank you very much!
