Why do we need to create a webmaster@ account?

[cw1586]

Iv installed wordpress and when a user sends an email using the contact form the whole email system takes a crap and nothing gets delivered. As the admin i get the following email sent to me.

The original message was received at Wed, 23 May 2012 18:48:47 -0700 from localhost

----- The following addresses had permanent fatal errors ----- webmaster@mydomain.org
(reason: 553 5.3.0 <webmaster@mydomain.org>... No such user here)
(expanded from: webmaster@mydomain.org.org)

----- Transcript of session follows ----- ... while talking to [127.0.0.1]:
>>> DATA
<<< 553 5.3.0 <webmaster@mydomain.org.org>... No such user here
550 5.1.1 webmaster@mydomain.org.org... User unknown <<< 503 5.0.0 Need RCPT (recipient)

Where is this webmaster@ username coming from? I dont have a webmaster@mydomain.org setup. Why should i have to do that?

I have one email address setup for mydomain.org and its admin@mydomain.org only.

So i setup webmaster@mydomain.org and tested my form. Now it works but this doesnt make any sense. Why do we need to create webmaster aliases with every domain we setup using ispmanager? :confused:

Hello, in the WWW domain properties in E-mail administrator field you should enter email and this email should be exist
This address used for email From:

Why does it need to exist? Sending FROM: admin@mydomain.com should be enough. Why do i need to create webmaster@domain.com too? This doesnt make any sense.

Can you explain why?

The other strange thing is i cannot send mail to the email address on the server where ispmanager is installed. When i do i get this;

Your message did not reach some or all of the intended recipients.

The following recipient(s) cannot be reached:

admin@domain.org on 5/23/2012 7:31 PM
Server error: '550 "Unknown User"

Not sure why this is happening. It works fine for the other domain, the 1st domain i created on the server but none of the email addresses for the second domain i created on the server.

The site is resolving since yesterday and i can send mail OUT. I just cant send mail TO. Any ideas what blocking it?

1. Change email address in WWW domain properties as you need. Email should be exist on server.
2.
Server error: '550 "Unknown User"
Check mail server logs
