Tommy,

The FROM header contains a name, including a comma, but is not enclosed within double quotes. This is a violation of RFC 822. Refer www.ietf.org/rfc/rfc822.txt section 3.3.

Here is an example of an incorrect header:

From: Doe, John <john.doe@example.com>

The correct way to specify this address in the From header is:

From: "Doe, John" <john.doe@example.com>

In short, a special character cannot appear in the email address unless enclosed inside a double quote.

Note that the actual name is encoded in Base64; therefore, you must decode it to see the embedded comma in your example.
