Unable to login into my mail account?

Using this link (http://www.howtoforge.com/virtual-u...x-courier-mysql-and-squirrelmail-ubuntu-12.10) I configured my Postfix mail server onto my Ubuntu 12.10 machine.
After completing the configuration, while I am trying to login i receives this error message.
"ERROR:
ERROR: Connection dropped by IMAP server"

Please guide me in this regard

 

I followed all the steps given in above link very carefully. And, didn't missed any step. I don't know why even then i am facing such problems ???

 

Are there any errors in your mail log (in the /var/log/ directory)?

 

Log is given below,please check and guide

Do you use the correct MySQL details in the /etc/postfix/mysql*.cf files?

 

Details of "/etc/postfix/mysql*.cf" files are given below. Please guide me that have I made any mistake in these configuration files.

nano mysql-virtual_domains.cf
“user = mail_admin
password = mail_admin_password
dbname = mail
query = SELECT domain AS virtual FROM domains WHERE domain='%s'
hosts = 127.0.0.1 “

nano mysql-virtual_email2email.cf
“user = mail_admin
password = mail_admin_password
dbname = mail
query = SELECT email FROM users WHERE email='%s'
hosts = 127.0.0.1 “

nano mysql-virtual_forwardings.cf
“user = mail_admin
password = mail_admin_password
dbname = mail
query = SELECT destination FROM forwardings WHERE source='%s'
hosts = 127.0.0.1 “

nano mysql-virtual_mailboxes.cf
“ user = mail_admin
password = mail_admin_password
dbname = mail
query = SELECT CONCAT(SUBSTRING_INDEX(email,'@',-1),'/',SUBSTRING_INDEX(email,'$
hosts = 127.0.0.1 “

nano mysql-virtual_transports.cf
“user = mail_admin
password = mail_admin_password
dbname = mail
query = SELECT transport FROM transport WHERE domain='%s'
hosts = 127.0.0.1 “

 

Are the MySQL details (username, password, database name) correct?
