||Although Poco doesn't support this at the moment Slaven has said he will look at this for a future release.
I haven't worked with attachments and scripting but it should be possible to achieve this functionality via a
script that runs on outgoing messages. You will have to store the attachment location information in the template
in some standard manner that you can determine from the script and you'll probably want to remove it in the script
that processes the outgoing message.
