postfix: relay by gmail

I have followed the Virtual Users And Domains With Postfix, Courier And MySQL (CentOS 5.1)
I don't have reverse dns, so i want to relay all my e-mail with gmail.
How to enable STARTTLS in postfix??

 

Does gmail allow relaying ? How do u plan to do this ? I think the howto enables STARTTLS by default.

 

Via SMTP.
Yes it does.

 

Okay in that case postfix does support postfix as a client authentication.

Add this to your config

Code:

 smtp_sasl_auth_enable = yes
 smtp_sasl_password_maps = hash:/etc/postfix/gmail_passwd
 smtp_sasl_type = cyrus
 relayhost = [smtp.gmail.com]:587

Create the file /etc/postfix/gmail_passwd

Code:

[smtp.gmail.com]:587            [email protected]:password

Then

Code:

postmap /etc/postfix/gmail_passwd
postfix restart

 

Yes it works! Thanks.
