be delivered to one or more recipients. It's attached below.

For further assistance, please send mail to postmaster.

Does the account exist in your mail server?

Yes, the account exist, for example if you write a mail to sendmail I don't have a problem but if I send a mail a Server Communigate Pro, always give me an error.

Any log in your Communigate Pro? You'd better check it too

Re: error sender unknown user account

My computer has a diferent name because I have created other virutal domail.
My virtual domain is vitual.org
My computer is local.server.org.
I thing the problem is when other server try verify the name this can't verify the mail because it don't find the virtual domain.
