Can MEG send a plain text message to recipient first without encryption. However, within a message sent also provides a link to download attachment from secure web mail later?
So only attachment will be stored on MEG. While I try to find an option on web GUI, however I cannot find what I describe above.
Someone might ask me why should we do that?
In real life, people don't want to download entire email every time they got a large one. They might want to know first what it's all by reading text first; then download big attachement later.
Especially, when downloading from sender MEG is quite slow and take a long time. That suits to the case where only attachments are truly confidential.
