I currently have 3 email addresses set up in Outlook. Why do I receive emails
from spammers addressed to email addresses that do not exist but do have our
company's domain name in them? Mostly, how can I set up Outlook so that they
go straight to junk e-mail?

The recipients listed in the To, Cc, and Bcc fields are NOT used when
routing the e-mail. The e-mail client compiles an aggregate list of
recipients from the To, Cc, and Bcc fields in its UI. For each
recipient in that list, the client sends a RCPT-TO command to the mail
server. After that, the client sends one DATA command containing the
*data* of the message which includes the headers and body inserted by
the client. The recipient never gets to see the list of RCPT-TO
commands sent to the sender's mail server. They only get to see the
headers that are in the *data* that the sender's client inserted into
the message and which are NOT used to specify the recipients. List
servers used for newsletters and bulk mailings never use the headers
within the data of the message. They get their list of recipients
completely separately of the e-mail's body.

That the domain in the recipient's e-mail address happens to be for your
domain is simply coincidental where spam is concerned. They may include
it to mislead the recipient into believing the mailing went specifically
and only to someone at that domain.

There are two possible situations I can imagine. The first is that your mail
server is programmed to accept any address whatsoever as long as the domain is
your company's domain and then deliver that message to one of your accounts.
The second is that the message was actually addressed to one of of your
addresses, but you were Bcc'd. What you see in the To field has no
relationship to the actual address of the message. Most mail clients make
sure the address in the To field is the actual recipient address, but there's
nothing that requires it. It's quite easy to send a message to an address and
have it look like it's addressed to someone else.

I can think of multiple ways. One way is to use a rule that moves messages
not addressed to one of your addresses to the Junk E-mail folder.
