Mysql database for email,

host=127.0.0.1
dbname=postfix
user=postfix
password= *********
Table =mailbox
User is =  user
Column password = password


vim /etc/dovecot/dovecot-sql.conf has the following

connect = host=127.0.0.1 dbname=postfix user=postfix password=*******
default_pass_scheme = PLAIN-MD5
password_query = SELECT mailbox as user, password FROM password WHERE 
email='%u';
