download attachment only on demand (imap)

[Uwe Brauer]

Hello

May be I am missing something, but I experience the following. 
I connect to my imap server via gnus and click on the message in order
to read it. Unfortunately that message contains quite a huge
attachment (which I did not know). Now gnus needs quite a bit of time
(using an old modem connection) in order to open the message. Once it
is open it takes almost no time to download the attachment, since, as
I presume it is already downloaded in some temp place.

Couldn't that behavior be changed? What I have in mind is that gnus
open the message, you can read the message body, but it starts only to
download the attachment when one clicks on it.

I wounder whether this behavior has something to do the way gnus is
configured (or hacked) or the way the imap protocol works.

Thanks and regards
