postfix: relay by gmail

[mexus]

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

 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

[smtp.gmail.com]:587            username@gmail.com:password

Then

postmap /etc/postfix/gmail_passwd
postfix restart

Yes it works! Thanks.

Hi, followed instructions but in ISPConfgi 3 I get this

...dsn=5.7.0, status=bounced (host smtp.gmail.com[74.125.130.109]] said: 530 5.7.0 Must issue a STARTTLS command first.

Is there anything I can do?

Thanks a lot!
