Just got an incident today where a user reports to have received a mails sent to another person
The mail is a phishing attempt
'UserA' got the mail
'UserB' was in the 'TO' field
Received: from mydomain1(xxx.xxx.xxx.xxx[xxx.xxx.xxx.xxx]) by mydomain2with SMTP (Microsoft Exchange Internet Mail
Service Version 5.5.2653.13)

Received: from SPAM-Domain- yyy.yyy.yyy.yyy by mydomain1 with Microsoft SMTPSVC(5.5.1774.114.11);
FCC: mailbox://supprefnum1816646952075 () wamu com/Sent
From: Washington Mutual, Inc <supprefnum1816646952075 () wamu com>
X-Accept-Language: en-us, en
As can be seen from the above, the mail is being sent to 'UserB'
How come 'UserA' got the mail? I know about spoofing the FROM field, but as far as I know the TO field is not spoofed
May be the header was manipulated, but the IP address in the RECEIVED part are OK
Is it a problem with my mail servers (you can see that Exchange is being used :) ?
Or is it a technique used by spammers?
Your views will be greatly appreciated
Thanks to all
