XRecipientList for MS Exchange 2000/2003

Purpose

An Exchange 2000/2003 mailbox may have multiple SMTP addresses associated with it. For example, John Doe has a mailbox with a primary SMTP Address of john.doe@company.com and secondary SMTP address of john2@company.com. John wishes for emails sent to his secondary SMTP address to be automatically placed in the separate folder he has created. To do that he can define in his Outlook a rule like this:

   Apply this rule after the message arrives
   with john2@company.com in the message header
   Move it to john2 folder

So far so good. But if a message sender uses BCC option or when John Doe gets a SMTP e-mail addressed to distribution group, his e-mail address is not placed in the To: or the CC: fields. Even more, his e-mail address does not appear anywhere in the message headers at all. As a result, the rule above can not work.

XRecipientList application inserts the actual (SMTP envelope) recipients to the mail header. The application adds a new header field named X-RecipientList to each inbound e-mail. X-RecipientList field contains the list of the SMTP envelope recipients. Based on this header information, user will be able to set rules using his/her e-mail client software (i.e. MS Outlook).

The application is a SMTP transport event sink.

Benefits

• The application is server-centric, so you do not need to install any extra software on the client side
• The application can be installed on any Exchange server computer or on the border server machine that communicates with external e-mail servers. If you run a single Exchange server, it is a border server by default

Limitations

The application will ignore the internal messages. When both the sender and the recipient of the message belongs to the same Exchange server, X-RecipientList header wont be created.

Installation

On your Exchange Server 2000/2003 computer:
1.Select (or create) user account that is a member of the local Administrators, Domain Admins and Domain Users security groups.
2. Log on locally as that user.
3. Create C:\Program Files\XRecipientList\ directory.
4. Download XRecipientList.zip archive file
5. Move XRecipientList.zip to C:\Program Files\XRecipientList\ directory and extract all files.
6. Run C:\Program Files\XRecipientList\regXRecipientList.bat

Testing

1. Open any SMTP/POP3 e-mail client (for example, Outlook Express), create a new e-mail message and place your own Exchange mailbox address (let's say JohnDoe@yourdomain.com) to Blind Carbon Copy (BCC) field. Send this message.
2. Using MS Outlook, open your mailbox. Make sure the message you just sent exists in the Inbox folder.
3. Open this message. Note that To: field contains "Undisclosed-Recipient:;" value. Select Current View > Options. Scroll Internet headers textbox to make sure the header "X-RecipientList: JohnDoe@yourdomain.com" exists.

Uninstallation

1. Run C:\Program Files\XRecipientList\unRegXRecipientList.bat
2. Delete C:\Program Files\XRecipientList\ directory.
