postfix : how to send mail to gamil account

[vivekraj.agrawal]

hello everyone,
I want to use postfix to send email to gmail accounts. Currently i am able to send and receive mail in my localnetwork. Can you please describe what will be next step if i want to send mail to gmail account.

on some sites i have read to use gmail account we need sasl certificates. i have tried creating sasl certificated 4-5 times. and i am getting error "peer name verification fail common name mistmatched : smtp.gmail.com.

Do we really require this gmail account sasl for sending new mails from localnetwork to gmail account.

thanks in advance

add this line to the bottom of your postfix transport file

* smtp:[smtp.gmail.com]

and check .

i have also used postmap transport command.
* smtp:[smtp.gmail.com]

This is the log after when i have use the command sendmail -bv vivekraj.agrawal@gmail.com
