Incoming mail from outside of our organization is randomly delivered to wrong mailbox.  The user's names are usually similar, ie Beth.Wrong@mydomain.org is getting mail sent to Beth.Right@my.domain.org.  In one instance where I looked at the mail headers, there was no reference to the address of the person who received the mail incorrectly.  Not sure if this is ALWAYS true, but in most of these cases, the mail is Spam.

A similar problem randomly occurs when using REPLY in Outlook.  In this case, the sender's email address is modified and given the domain name of my organization.  I receive mail from Outsider@TheirDomain.net and when I REPLY, my reply is addressed to Outsider@MyDomain.org.  Of course I get a NDR.  When I look at the headers I see
(envelope-sender <Outsider@TheirDomain.net>)
From:  Outsider@MyDomain.org
Return-Path:  Outsider@MyDomain.org

Are these 2 problems related?  Does anyone have a suggestion for resoving either?

Hi,

If you have a POP mailaccount you can set this up for yourself. If you add another answering address than your mailaddress, people will be sending to this e-mail address if they hit the reply button (not your own e-mail address) so this could explain the spoofing (wronly getting e-mail).

Also, there are a lot of spybots looking and seacrhing on the web for e-mail address. So if user Beth Wrong posted a question (or maybe even requested some sort of free service on the net) and used Beth Rights e-mail address, then mail for Beth Wron will be send to beth.right@domain.com...

You can do nothing about the incoming mail, accept making sure that you have got good spam filters. If you mail this user internally (with the SMTP address) and she receives the mail, than nothing's wrong with the mail server...
