postfix: Relay access denied
I'm running postfix and courier-pop-ssl on a debian etch 2.6.18 .I have a dynamic ip and a domain name.
Mails get rejected with a Relay access denied and that's what logs say:


Dec 19 12:29:39 localhost postfix/smtpd[3840]: connect from[]
Dec 19 12:29:40 localhost postfix/smtpd[3840]: NOQUEUE: reject: RCPT from[]: 554 5.7.1 <>: Relay access denied; from=<> to=<> proto=ESMTP helo=<>
Dec 19 12:29:40 localhost postfix/smtpd[3840]: disconnect from[]

and also a # postconf -n :

I'm also going to configure an anonymous remailer so i wouldn't set too strict rules about relaying mail through my mail server and offcourse i wouldn't be an openrelay for the bloody spam ... i did it before and i don't know why it's not working this time . Anything else you need to know just ask , thanks !!!!

is Google your ISP ? If not, then why would they allow you to relay mail off their server without knowing who you are ?

you need to use the Mail server of YOUR isp as a relayhost, not googles mail server. Your ISP will know who you are because your public IP address will be from their IP Address pool.. Typically that is all the authentication they need.

It looks like you just need to add $mydomain to mydestination.

Google is not my isp ( ... it's a search engine ... ) and i always used it sucessfully as a relayhost .

google runs open relays? :scratch:

That is what I was thinking at first, but it looks as though he's authenticating against the Google mail server with his gmail account information.

so I would check the /etc/postfix/sasl_passwd file make sure the authentication info is correct, and then verify postmap was run against it and try again...

Thanks farslayer your link was helpfull , my mail server is working now i can relay mail to my gmail account and everything else is working as expected , cheers !!!!

I think people have misunderstood the logs. It's gabsik's mailserver that rejected google, not the other way around. postfix rejected mail to admin@$mydomain because $mydomain wasn't listed under mydestination.
