Hello! Please, help! I have trouble with Dovecot's Deliver utility. I don't know how to avoid errors. Let me know what additional related information do you need?

1. Its call in Exim's configure:

   local_delivery_spam_transport: driver = pipe command = /usr/local/libexec/dovecot/deliver -c /usr/local/etc/dovecot/dovecot.conf -d $local_part@$domain -m Junk message_prefix = message_suffix = log_output = true delivery_date_add envelope_to_add return_path_add user = mailnull group = mail

2. maillog output:

3. dovecot-mysql.conf

   driver = mysql connect = host=localhost dbname=exim user=exim password=***** default_pass_scheme = PLAIN password_query = SELECT username as user, password FROM users WHERE username = '%n@%d' AND active='Y' user_query = SELECT home, 26 AS uid, 26 AS gid FROM users WHERE username = '%n@%d' AND active='Y'

4. Owner and permissions on mailbox-directory:

   /usr/local/etc/exim> ll /var/mail/exim/runoguy.ru/ total 6 drwxrwx--- 10 mailnull mail 512 Nov 13 10:40 eyatsko drwxrwx--- 5 mailnull mail 512 Nov 12 22:17 nkolobovnikova drwxrwx--- 5 mailnull mail 512 Nov 12 22:30 oyatsko /usr/local/etc/exim>

5. Junk folder:

mailnull has system uid=26, mail has system gid=26.
