[satish]

Dear All,

I have installed koha (localhost)  on the laptop with  Debian Squeeze
2.6.32-5-686 - Koha 3.10.03 and connected to internet with broadband
(ISP).

I would like to know, Is it possible to  configure Postfix with koha
for sending overdue mails using gmail.

I have checked the following URL:
http://kohageek.pbworks.com/w/page/58731341/Configure%20gmail%20with%20postfix%20to%20send%20notices%20from%20Koha

and followed the same.but, No success.

settings of the file:  mail.cf

root at Shankara:~# postconf -n
append_dot_mydomain = no
biff = no
config_directory = /etc/postfix
readme_directory = no
relayhost = [smtp.gmail.com]:587
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options = noanonymous
smtp_tls_CAfile = /etc/postfix/cacert.pem
smtp_use_tls = yes
smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
