Hello Team,<br />
<br />
I would like to know what is the proper method to set up a postmaster@domain.com mailbox in an Exchange 2010 Environment. I already configured it Organization Configuration &gt;&nbsp;Global settings tab &gt;&nbsp;Transport Settings &gt;&nbsp;&quot;External postmaster address&quot;, which I entered my personal email address in that field. Although when I send a message to postmaster@domain.com I don't receive the email, I receive a bounceback that the user postmaster does not exist. <br />
Am I supposed to create a user account for postmaster@domain.com in my domain and enable an mailbox for it just like I do with any user account?<br />
<br />
Thank you!

Hello Team,

I would like to know what is the proper method to set up a postmaster@domain.com mailbox in an Exchange 2010 Environment. I already configured it Organization Configuration > Global settings tab > Transport Settings > "External postmaster address", which I entered my personal email address in that field. Although when I send a message to postmaster@domain.com I don't receive the email, I receive a bounceback that the user postmaster does not exist. 
Am I supposed to create a user account for postmaster@domain.com in my domain and enable an mailbox for it just like I do with any user account?

Thank you!
