I vote for Exchange ...
Would the add-in be compatible with IIS SMTP too?
An event sink could be designed to intercept messages for both Exchange and IIS. This way any email server that can forward a message can reach Splendid. For example, a message sent to support@domain.com on a company's existing MailEnable server could get forwarded the Splendid SMTP(Exch or IIS) with an address like GUID@splendidserver.domain.com.
Paul - where do you envisage plugging into the Exchange architecture?

Your point about IE specific javascript is well taken, but we simply do not have the resources to test the application on any other platform. Most of our javascript is generic, but if you find an area that could be coded better to support Firefox or Opera, please feel free to send us a fix.
Thanks for your opinion on the use of Exchange Server. Every vote counts.
