I'm getting a strange error on certain email addresses I send to, I'm using Outlook 2003 on Vista and as soon as I click send, almost instantly I get the following error:

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

      Subject:      Website
      Sent:      01/05/2009 11:04

The following recipient(s) cannot be reached:

      'enquiries@*******.co.uk' on 01/05/2009 11:04
            550 sorry, no mailbox here by that name (#5.1.1)

Now this mailbox definitely exists as I can send using my email account in a web based program.

The strange thing is I get the email almost immediately after I've clicked send, it goes to the outbox, disappears and voila this email is in the inbox, it's as if it never even leaves the server!

The email comes from System Administrator and has a strange circular icon in Outlook with a red arrow? I'm not using Exchange or anything like that, 9 times out of 10 emails will go without a problem.

Thanks in advance.

There is a couple of reasons that a mail server could give you back a 550 error. If you are using a client to send email you have to configure the client to authenticate before sending the email. Almost every mail server doesn't accept relays. Also I would recommend doing a nslookup on the domain you are trying to send to. Note all of these are basically run from the command line.
nslookup
set type =mx
domain.com

and then open a telnet to that particular domain. So if that command returns a 1.1.1.1 then you do:
telnet 1.1.1.1 25

You should receive a 220 followed by a banner.
You can then type
helo
this will return a 250 if successful.
mail from:<myaccount@mydomain.com>
250 again if successful
rcpt to:<targetuser@targetdomain.com>
250 if successful.

Keep in mind that some user networks have been completely blacklisted.
