I have a request from my users which I hope that you can assist me with.

Basically, we need to use IMAP, but we receive large emails with big attachments. What we need is for the whole email to be downloaded in the background so that when it appears in the message viewer it is already downloaded.
Essentially, the client needs the emails to not appear in the message list until it has completely downloaded in the background.

I hope that someone can assist me with this one, my users are driving me nuts!
