550 5.1.1 User Unknown error (but the user is known)

Asked by tnorman in Email Clients

Tags: 550, user, unknown

I have a client ("John") who is having troubles receiving email from one particular person ("Fred").  When Fred emails John, or anyone at John's company, he gets this email message back:

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

      Subject: (subject)
      Sent: 2/19/2004 3:15 PM

The following recipient(s) could not be reached:

      'John' on 2/19/2004 3:15 PM
            550 5.1.1 <john@domain.com>... User unknown

Everyone else in the world can mail John.  I have checked and double checked the spelling, etc.

We are currently using 'IMail', but have been assured by their tech support that the problem is not at our end.

Any input, etc. would be appreciated.

Thanks,

TN
