Exchange mailbox may have multiple SMTP addresses. For outgoing messages Exchange server always uses the primary SMTP address. For example, John Doe has a mailbox with primary SMTP address and secondary smtp address. John Doe can easily receive the message addressed both to and, but he can not send the message as because this behaviour is by design in Exchange server.
ChooseFrom for Microsoft® Exchange 2000/2003 application allows users to send a message with any of their own SMTP addresses as the From address.
This version of ChooseFrom is compatible with Sunbelt Ninja antispam/antivirus software.
The application is a transport event sink.

Current version:



On your Exchange server computer:
1. Select (or create) a user account that is a member of the local Administrators, Domain Admins and Domain Users security groups.
2. Log on as that user.
3. Create C:\Program Files\ChooseFrom\ directory.
4. Download archive file to C:\Program Files\ChooseFrom\ directory and extract all files.
5. Run C:\Program Files\ChooseFrom\regChooseFrom.bat.


1. Make sure your mailbox has more than one SMTP address. Ask your Exchange admin to add the following additional SMTP address:
to your mailbox.
2. Open Outlook and create a new mail message. Click View->Options and fill "Have replies sent to:" field with
      ChooseFrom settings picture
Click Close button.
3. Send your message to any external Internet address you can operate.
4. Receive the message you have just sent using any SMTP/POP3 e-mail client (for example, Outlook Express).

5. Make sure the sender address (the From: field) is (without "smtp:" prefix!).

ChooseFrom application has been tested with Exchange 2000 SP1/SP2/SP3 on Windows 2000 Advanced Server and with Exchange 2003 SP1/SP2 on Windows Sever 2003.


By default users can send as their own SMTP addresses only.
However, it is possible to bypass this limitation by creating a security group named SENDASANYONE and placing there the user accounts you wish to be able to send as anyone.

Side Effects

The main side effect is that you can not exploit Outlook "Have replies sent to:" field as usual. If an outgoing message has the reply-to address filled out, ChooseFrom will set this address as the From: field and the Reply-to: field will be removed completely.

Client-side application that can cooperate with ChooseFrom

There exists an Outlook utility named SmartReply that allows an Outlook user the ability to easily select the From address of the new, replied or forwarded message. SmartReply 2007 can work on Outlook 2003 and Outlook 2007. SmartReply 2010 is compatible with Outlook 2010.


1. Run C:\Program Files\ChooseFrom\unRegChooseFrom.bat
2. Delete C:\Program Files\ChooseFrom\ directory.
