SYMPTOMS

When the Windows client receives a message from the SMTP gateway that contains a comma in the comment field of the address in the To: or Cc: field, the address is delimited by the comma and a Non-Delivery report is generated. No mail is misdirected or lost.

CAUSE

The Windows client incorrectly uses the comma to delimit the address on the To: or Cc: field. For example

To:<Administrator (comment,comment)>

becomes two addresses resulting in

To: Admin; Comment)>;

The portion of the address following the comma is treated as a bad address and a Non-Delivery report is generated.

RESOLUTION

The sender should edit the address in the To: or Cc: field and exclude commas in addresses.

The address appears correctly in the MS-DOS client until the Mail for Windows client accesses the message. To read the message, use the MS-DOS client.

STATUS

Microsoft has confirmed this to be a problem in version 3.2 of Microsoft Mail for PC Networks. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
