Hello mouss, Thanks for your kind help. I am now in a position to give you some really good news. When I was looking close to my logs and got the error "can not connect to port 25" then your mail arrived and enlighten me. I have modified my main.cf as below #inet_interfaces = localhost then the master.cf as below smtp inet n - n - - smtpd submission inet n - n - - smtpd -o smtpd_etrn_restrictions=reject -o smtpd_client_restrictions=permit_sasl_authenticated,reject smtps inet n - n - - smtpd -o smtpd_tls_wrappermode=yes smtpd_sasl_auth_enable The good news is after restarting the postfix the mail server is collecting the emails from the net. The unsolved one is smtps is still not working. I have tried the either way too as you suggested to use TLS but both the cases it says can't connect to the smtp server. The mail.warn log provides a message postfix/master[1912]: warning: /usr/lib/postfix/smtpd: bad command startup -- throttling with regards, -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Joydeep Bakshi, Linux System Admin Kolkatainfoservices Pvt Ltd, 23A Royd Street, Kolkata 700016, India Work Phone 91 033 40014784 http://infoservices.in/ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
