550 reject code

[Myinzu]

My email users are getting the message ( Please see below ).

(e-mail address removed) on 10/6/2007 11:33 AM
The e-mail account does not exist at the organization this
message was sent to.

Check the e-mail address, or contact the recipient directly to find out the
correct address.
< mangiafuoco.cs.interbusiness.it #5.1.1 SMTP; 550
<[email protected]>: Recipient

address rejected: User unknown in virtual mailbox table>
-- -----------------------------------------------------------

********I need to track it down where those messages are originating from
and look for a solution to the fix.

I'm sure it is a normal and informational message but it goes out to almost
all users in the organization. I guess something like this should be in the
log only.

Please advise. Thx in advance.

So are you asking about Outlook or about some error message your mail
server is issuing? This newsgroup is for Outlook which is an e-mail
client, not a mail server.

I was not sure if this is a Outlook/Exchange/SPAM filter issue. It looks like
it's mis-categorized. Should I post it to Exchange queue. ??

Looks to me like an NDR (non-delivery report) e-mail that you got back
after trying to send to a recipient that is not defined at the
destination mail host. "e-mail account does not exist" pretty much
means the receiving mail host is saying user "lo" is not defined at
domain "lca-cagliari.it". You say "users" are getting this NDR. Does
that mean senders to YOU are getting back this NDR? Is
(e-mail address removed) you or them?

I don't know what the "address rejected: User unknown in virtual
mailbox table" error means. Virtual mailbox? So is this your account
but you are using an alias to it, it is a shared mailbox (i.e., more
than one username can log into the same mailbox), or perhaps some
e-mail service from a webhosting service where you have your web site?

Hi,

My users never sent anything to (e-mail address removed)

They get returned mails with the (e-mail address removed) recipient not being
reached.

That's certainly not the EXACT text of the error. Post the exact text.
