Hi,
Unfortunately I do not have a sample of the .eml files but they will include attachments. This will be part of a larger solution based on Microsoft SharePoint. Emails will be sent to a SharePoint document library. This library will have an event handler on it that converts the .eml files to .msg files and move them to a different library, as well as copy the attachments out to a second library.
We are expecting approximately 20,000 emails per work day (approximately 12 hours because its across a few time zones). The only thing we will use Aspose for is to convert the .eml files to .msg files and to copy the attachments out.
Thanks.
