Relay Access Denied, No Valid Recipients etc for Postfix Email setup Pls Help!

[unixaunixa]

Hi,

I am desperate I have spent three weeks trying to set up my email server on my hosted ubuntu server and cannot send email! I used the ubuntu how-to setup guides and also set up my MX entries using DNS.

I can do "telnet locahost 25" and email successfully, but cannot send email from outside clients! Pls help me. I am desperate at this point and need the email for my company.

Pls let me know which configuration files I should post. I looked at various other forums and tried the tips, but nothing has resolved the issue for me. I am using shadow authentication for user accounts. Ubuntu 10.04.2 using Postfix w/saslauthd

Thanks,

U

You will need to post more information I'm afraid.
Pretty obvious that jmc-worldwide server is not set to allow relay messages from the client.

Could be lots of reasons for that, but as you don't say where the error is from, or what the client or email server are, it is all a bit moot.

If you are trying to send email from an internal network to the internet, you will need to permit relaying from local clients, I think it is disabled by default in Postfix.

This doc might give you some clues

Thanks for responding! Perhaps the following details may assist.

1. Where the error is from? Emailing to the address from an external email web client. It also fails when I use netcat. Example:
...
netcat mail.myserver.com 25
220 s15343205.onlinehome-server.com ESMTP Postfix
ehlo myserver.com
250-s15343205.onlinehome-server.com
250-PIPELINING
250-SIZE 10240000
250-VRFY
250-ETRN
250-STARTTLS
250-AUTH PLAIN LOGIN DIGEST-MD5 CRAM-MD5
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN
mail from: root@myserver.com
250 2.1.0 Ok
rcpt to: queen@myserver.com
554 5.7.1 <queen@myserver.com>: Relay access denied
...

2. Email server is Postfix email server. See main.cf below.
