I'm new to sending email with SBB and I'm wondering how to send an email with a file attachment that is already Base64 encoded. Do I need to decode it, add to the ContentStream and let the routines Encode it again or is there a way to signify that the attachment is already encoded?

Thank you for contacting us.

That's right. Unfortunately there is no way to instruct TElSimpleMIMEMessage class that the data stream is already encoded using base64. So if you have such stream, you need to decode it first.

The question really is about how exactly the recipient should handle the data.

If you have the base64-encoded data that must remain encoded on the client side, when the recipient saves them to the disk or processes them otherwise, then you need to attach the data as is (not matter that they are encoded now) and this data will be encoded for the second time, but the recipient will remove first encoding and have your "original" encoded data.

If you want the recipient to see the non-encoded data, then your way is correct but there's no way to do this with TElSimpleMIMEMessage now.

Sincerely yours
