Postfix - 550 550 #5.1.0 Address rejected

[Zidaps]

When I enter: sudo lsof -nP -i :25
not running a firewall and the router has 25 open / forwarded to the server.

Here are my results:

COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
master 8389 root 12u IPv4 3149454 0t0 TCP *:25 (LISTEN)
master 8389 root 13u IPv6 3149456 0t0 TCP *:25 (LISTEN)

Bump!! help setting up mail server.. please.

So I am still struggling to figure this stuff out...
Seems like my configuration is good, but I can't seem to send or receive mail.

my telnet connection works: (ip address and domain name below changed)

zidaps@localhost:~$ telnet example.com 25
Trying 209.107.204.13...
Connected to example.com.
Escape character is '^]'.
220 localhost.example.com ESMTP Postfix (Ubuntu)

the ehlo bit works as well:

ehlo example.com
250-localhost.example.com
250-PIPELINING
250-SIZE 10240000
250-VRFY
250-ETRN
250-STARTTLS
250-AUTH CRAM-MD5 DIGEST-MD5 PLAIN LOGIN NTLM
250-AUTH=CRAM-MD5 DIGEST-MD5 PLAIN LOGIN NTLM
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN

What am I missing here? Why isn't the mail being sent or received from my example.com ??

This is the error I am getting from gmail:

Mail Delivery Subsystem mailer-daemon@googlemail.com to me
Delivery to the following recipient failed permanently:

info@example.com

I'm not sure what other valid info I can provide?? here is my main.cf file again:

Ok, so a bit of progress but still a no go..
I've added the MX record information for my ISP at my godaddy account.

But now I am having another error returned:

Delivery to the following recipient failed permanently:

username@mydomain.com

Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 530 530 authentication required - for help go to http://help.yahoo.com/help/us/mail/pop/pop-11.html (state 13).

I think Rogers is your problem. Outgoing mail could be due to a local configuration problem but it looks like incoming mail is being rejected by your ISP. Doesn't Rogers require you to use @rogers.com e-mail addresses?

You have two options in my estimation:

1. Find someone successfully using Postfix and Rogers to advise you.
2. Dump Rogers.

My preference is the second one. A few years ago I struggle to get Postfix/Rogers working. It worked only a short time and then Rogers started requiring a list of Sender e-mail addresses. I am down to two mobile phone accounts with Rogers. One will probably be cancelled in the next week or so. The other one probably soon after.

Zidaps, if you are in Ontario, Canada, I can give you the specs for my ISP... and no, I have not vested interest in my ISP.

Hi Dennis,

Thanks for the help. Yes I am in Ontario. If you can send me the ISP config information that would be awesome. If it works with that then we know for sure the problem is Rogers. (wouldn't be surprised)

but I want to believe there is something else I am doing wrong.. Reason being. I am using openwebmail to access and send my mail... I am not even able to send mail locally on my own network. I have 2 user names created on my server and using that to try to send mail from between users on the same domain.. but its not working. It says the mail is sent successfully, but the other user doesn't receive it... I will post the mail log error when I get back home tonight.

Thanks.

Are you actually using the domain example.com? Your ISP may very well recognize that you are not the owner of example.com so it refuses to relay mail with that address.

[Zidaps]

Hi hawkmage,

no i'm actually using my domain name torontotuner.com so i'm not sure what the issue is or could be.

[hawkmage]

OK, for your domain I see that you have the following MX records:

torontotuner.com    mail exchanger = 0 torontotuner.com.
torontotuner.com    mail exchanger = 0 smtp.broadband.rogers.com.
torontotuner.com    mail exchanger = 10 mailstore1.secureserver.net.

You have your Mail server reports its self as bluesteel.torontotuner.com and you have no DNS entry for it.

You may want to have postfix report its self as torontotuner.com or add an externally resolvable entry for the name bluesteel.torontotuner.com.

I sent an email from my system to admin AT torontotuner.com with the subject "This is a test". Did you get it?

[Zidaps]

Hi Hawkmage,

So i tried changing my hostname definition in postfix to read just torontotuner.com but that didn't work. Unfortunately I did not get the email from you either. The reason I have the defined myhostname as bluesteel.torontotuner.com is because my machine's name is BlueSteel... All the tutorials show that I should make it localhost.domain.com

So far no luck.. I will keep trying new things to see what works. If you have any suggessions.. by all means... Please let me know Thanks.
