Post is really too vague to comment.

Please make it clear what elements of this issue you control.

Is this a mail server which you control? If so, what Operating System and mail service engine?
Does it normally work?

Is this an internal mail server or one which is connected to the Internet?

What email client does your boss run, and on what Operating System? Whatever email client, please be specific about the software name and version.
Do all your email clients have commercial virus scanners?

To progress this problem we need to be able to display representative email headers without endangering the client computer if they are viral. This is much easier if we can catch the email on a unix email server. If it is a M$ email server it will require M$ expertise.
