sparticat,
If that's the case, then you can try using a PlanetPress Image output instead of a PlanetPress Fax output. Use the same form that you are using with PPFax, and make sure you check the option "Send Email". Then go to the Login tab, and choose either Outlook or SMTP, whichever you want to use(in your case, I think it's Outlook). Then, in the Recipients tab, you will enter the email address that you want to use. Use the format you've described above. You can also make variable data selections from your input data, if you want the user name to be variable. Please bear in mind that you can only select one user name, because it will treat the data file as one big file rather than treating multiple records separately. A workaround for this would be to use a splitter to split your data every records...
After that, the last step is to go to Attachments tab, and check "Attach output file", which will attach the file generated by Image to the email that is sent. And that should be it. If you run this process, it will send the email to Outlook, which will then forward it to the proper recipient. (the actual emailing is done by Outlook, not Image)
