problem dovecot+postfix+mysql+postfixamin+sasl2

Good evening I have the following problem, configure dovecot + postfix + mysql + postfixamin + sasl2+courier-imap, could well set the imap folders connect with postfixamin accounts, but to send by smtp I have not been able to do, just send to the users of the system, my files configuration:

1.- dovecot.conf (/etc/dovecot):
## Dovecot configuration file
# Protocols we want to be serving.
protocols = imap pop3 lmtp
mail_location = mbox:~/mail:INBOX=/home/vmail/%u
log_path=/var/log/dovecot.log

dict {
quota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext
expire = sqlite:/etc/dovecot/dovecot-dict-sql.conf.ext
}

# Most of the actual configuration gets included below. The filenames are
# first sorted by their ASCII value and parsed in that order. The 00-prefixes
# in filenames are intended to make it easier to understand the ordering.
!include conf.d/*.conf

2.- dovecot-sql.conf.ext (/etc/dovecot):

driver = mysql
connect = host=localhost dbname=postfixadmin user=postfix password=postfix
default_pass_scheme = MD5-CRYPT
password_query = SELECT username as user, password, concat('/home/vmail/', maildir) as userdb_home,concat('maildir:/home/vmail/', maildir) as userdb_mail, 502 as userdb_uid, 12 as userdb_gid FROM mailbox WHERE username = '%u' AND active = '1'
user_query = SELECT concat('/home/vmail/', maildir) as home, concat('maildir:/home/vmail/', maildir) as mail, 502 AS uid, 12 AS gid, CONCAT('*:messages=10000:bytes=', quota) as quota_rule FROM mailbox WHERE username = '%u' AND active = '1'

3.- auth-sql.conf.ext (/etc/dovecot/conf.d):

# Authentication for SQL users. Included from auth.conf.

passdb {
