Hi,
Are you using any spam filter for exchange? I.e-Symantec mail security for exchange.  If so, look at the license status and see whether it's expired?

That is called email address spoofing... making it look like email originates from within your domain.  If you check the email headers, you'll see that the sending email server will not be your domain server but probably one that does not exist or is found in China.
 
One thing spammers are doing is using the CEO's address when spoofing to try and make the email legitimate enough that the employee will click on the link or document that delivers the malware payload.
 
As Radhakrishnan says, you need a good third party email spam control program.  I use OnlyMyEmail... simply excellent.  I am in no way affiliated with the company except as a satisfied user.  My boss would readily pay double, it's so much better than the others.

Email spamming is a variant of bombing and refers to sending email to hundreds or thousands of users, May be combined with email spoofing, which alters the identity of the account sending the message, making it more difficult to determine from whom the email is coming.  Make sure you have Antivirus and Antispam software are necessary to detect, contain and notify whenever malicious code is detected.

Get a better anti-spam package.  I am no fan of Symantec or McAfee even when it is allegedly up and running... too much spam through the sieve and too many false positives.
