Customized e-mail distrubution list for

What I need to do is create a distrubution list that does the following:

Every e-mail address is different, but the subject and the message is the same. Now there is a attachment that needs to be attached to each message and every e-mail addressneeds to have a different attachment.

I know very tricky, and I don’t know if it can be done, but if ANYONE has anyinfo on how I could do this, could you please reply. I don’t care if I need to buy a 3rd party program, it just needs to get done.Running Groupwise 5.1 and 5.2. Don’t want to send the e-mail seperatly, just make it so that possiably we can drag the file to the e-mails on the list.

thanks in advance!
