Right then,

I've searched the internet high and low for an answer to this problem but cannot find one!

I have an ASP.NET application. From this application I need to add functionality that opens a blank email on the client with an attachment added.

I need to open a blank email, because the recipients are not known (i.e the user will enter recipients manually). There is no way (as far as I can see) that the System.Net.Mail namespace can do this (sending email with attachments if the recipients are known is a doddle).

I have cobbled a workaround using the mailto?Attach=filename functionality which works for some users and not others in my organisation.

Has anybody ever needed to be able to do this? Can anyone help!?

TIA
