Postfix 554 relay access denied!

[willebanks]

Hello all,

Well I have been racking my brain for days now and I can't figure this one out! Every one of the user email addresses I have setup with ISPConfig can send mail no problem! But not one of them can receive any mail. I keep getting the same error message!

xxx.xxx.xxx.xxx does not like recipient.
Remote host said: 554 <myusername@example.org>: Relay access denied!

I have removed my ip address as I am already getting enough jerks trying to break in to my system just fill in the x's with number and you know what I mean! I have checked all the setting in the main.cf file and everything looks o.k. based on what I have read...

I am using the Fedora Core 5 Perfect setup! I know it's probably something simple but the solution eludes me!

Is the domain that shall receive this email listed in the file /etc/postfix/local-host names? Does the website www.yourdomain.com has a co-domain yourdomain.com with empty host field, if not, create this co-domain.

Hey till,

Yes all domains are listed in local-host-names file and the co-domains are present as well!

If you're using Outlook or Outlook Express as your mail client, you will have to check "Server requires authentication" in the smtp settings.
